Creation of the Project-Team: 2020 March 01
Each year, Inria research teams publish an Activity Report presenting their work and results over the reporting period. These reports follow a common structure, with some optional sections depending on the specific team. They typically begin by outlining the overall objectives and research programme, including the main research themes, goals, and methodological approaches. They also describe the application domains targeted by the team, highlighting the scientific or societal contexts in which their work is situated.
The reports then present the highlights of the year, covering major scientific achievements, software developments, or teaching contributions. When relevant, they include sections on software, platforms, and open data, detailing the tools developed and how they are shared. A substantial part is dedicated to new results, where scientific contributions are described in detail, often with subsections specifying participants and associated keywords.
Finally, the Activity Report addresses funding, contracts, partnerships, and collaborations at various levels, from industrial agreements to international cooperations. It also covers dissemination and teaching activities, such as participation in scientific events, outreach, and supervision. The document concludes with a presentation of scientific production, including major publications and those produced during the year.

2 Overall objectives
2.1 Objectives
Aviz (Analysis and VIsualiZation) is a multidisciplinary project that seeks to improve data exploration methods, techniques, and tools based on Interactive Visualization. Visualization, in general, refers to the graphical representation of data or concepts to aid access, distribution or explanations of data. Card et al. give a general definition for visualization as
“the use of computer-supported, interactive, visual representations of data to amplify cognition.” 51
Taking this definition, visualization is a means of creating visual aids that lead to insight in the underlying data sets. It is not about producing nice pictures but about making data understandable and explorable so that visualizations help viewers gain knowledge about the data. It is about aiding the process of forming a mental model for the acquired data and so helping the viewer to understand underlying concepts, patterns, and connections within the data 71. In partiular, visualization has the goal to improve humans' sensemaking of complex data by taking advantage of the capabilities of their vision system: visual information can be processed in parallel and with a high bandwidth into the human cognitive centers 79. Ware defines five advantages of visualization 79:
- Comprehension: Supports the comprehension of large amounts of data.
- Pattern Perception: Previously unnoticed properties of data may emerge.
- Problem Analysis: Problems within the data may become immediately apparent.
- Adaptability: facilitates understanding of large- and small-scale features of data.
- Interpretation: Hypothesis formulation is facilitated.
Visualization encompasses the display of data, either real or simulated, from large information spaces or information systems that can be structured or unstructured, and augmented with automatic techniques such as machine learning. Basic visualization techniques include surface rendering, volume rendering, animation, satellite photographs, fluid flows, as well as network data, multi-dimensional tables of abstract measurements, unstructured data such as text, and even models closely connected to data. The Aviz team has expertise in all these areas of visualization.
The conceptual Data Analysis Pipeline related to four of the themes of AVIZ.
As shown in Figure 1, visualization deals with the data analysis pipeline and research in visualization has been addressing all the stages with less emphasis on the two initial ones and the last one. In its initial incarnation, Aviz has been focusing on interaction in combination with visualization, physical presentation, and perception. We now want to expand our research to wider questions, both in the human-side and in the system side. For the human side, we want to better understand human perception and cognition to improve the visualization techniques, so as to better convey information to the human brain. We also want to better understand the human biases to overcome them when possible, or provide methods to avoid them otherwise.
On the system side, we want to expand the scope of visualization that is currently limited to relatively small datasets and relatively simple analytical methods. To achieve scalability in visualization, we will focus on a paradigm shift: progressive data analysis. Long-running computations currently hamper the exploration and visualization process because human's attention is limited by latency constraints. We want to design exploratory systems that provide continuous feedback and allow interactions at any time during computation. The new progressive data analysis paradigm offers these capabilities, but to be usable, it requires the whole analytical pipeline to be re-implemented, and visualization and interaction techniques to be adapted.
2.2 Research Themes
Aviz's research on Visualization and Visual Analytics is organized around five research themes, described in more detail in the next section. Instead of addressing point problems, each research theme will address several stages of the visualization pipeline in a holistic manner, as summarized in fig:diagram.
1. Progressive Data Analysis and Scalability will address visualization scalability problems. Existing data analysis systems (such as Tableau 72, R 73, or Python with its data analysis ecosystem 59) are not scalable for exploratory analysis because their latency is not controllable. This theme will lay out the foundations of progressive data analysis systems, which generate estimates of the results and updates the analyst continuously at a bounded pace. It will focus on all the stages of the data analysis pipeline: data management mechanisms, data analysis modules, as well as visualizations, perception, understanding, and decision making 53
2. Physicality in Input and Output will seek to better understand the benefits of physicality for information. Although beyond-desktop environments for visualization are generating more and more interest, theories and empirical data are lacking. This theme will consolidate the nascent areas of data physicalization, situated visualization, and immersive visualization.
3. Perception, Cognition, and Decision Making will study how we perceive and understand visualizations in order to develop generalized guidelines for optimizing effectiveness. It will generalize results obtained with simple charts to more complex visualizations of large datasets, establish theories on the use of abstraction in visualization, and contribute new empirical knowledge on decision making with visualizations.
4. Methodologies for Visualization Research will develop new methods to ground the study of the above scientific questions, and to benefit visualization more generally. This theme will develop evidence-based strategies for communicating quantitative empirical findings, and will promote methodological discussions and open research practices within the field.
5. Visualization Techniques. This research direction is more general than the ones above. We study several dedicated visualization approaches that intersect with our major goals above but adress more generic issues related to creative visualizations and interactions in general.
3 Research program
3.1 Research Axis 1: Progressive Data Analysis and Scalability
Permanent involved: Jean-Daniel Fekete
Scalability is a major issue in visualization, although the problem has never been well defined until recently 67 and has received less attention in visualization than in other data-science related domains.
While data analysis has made tremendous progress in scalability in the last decade, this progress has only benefited “confirmatory” analysis or model-based computation; progress in data exploration has lagged behind. Existing data analysis systems do not support data exploration at scale because, for large amounts of data or for expensive computations, their latency is not controllable: computations can take minutes, hours, even days and months. Cognitive psychologists have shown that humans' cognitive capabilities degrade when latency increases 65, 70. Miller 65 points out that the feedback of a system should remain below 10 seconds to maintain the user's attention. Therefore, to try to limit the latency, analysts currently resort to complex, inefficient, and unsatisfactory strategies, such as sampling with its issues related to representativity and information loss.
To address the scalability problem under controlled latency, instead of performing each computation in one long step that forces the analyst to wait for an unbounded amount of time, a progressive system generates estimates of the results and updates the analyst continuously at a bounded pace. The process continues until the computation is complete, or it stops early if the analyst considers that the quality of the estimates is sufficient to make a decision. During the process, a progressive system allows users to monitor the computation with visualizations and steer it with interactions.
While the topic of progressive data analysis has started to emerge in the late 90's, it has remained marginal practically because it touches three fields of computer science that are traditionally separate: data management, data analysis, and visualization. Research on progressive data analysis remains fragmented; the solutions proposed are partial and the different solutions cannot always be combined. We have organized a Dagstuhl seminar on Progressive Data Analysis and Visualization 52, 74 that acknowledged the harm of this topical separation and devised a research agenda. Aviz will participate in this agenda with specific assets and published a book about the topic 3 to explain the problems and create a research agenda.
Aviz is actively working on designing and implementing the ProgressiVis language that is natively progressive 54. The language relies on a Python interpreter but its execution semantics is different in the sense that all the operations that would take time to execute are performed progressively. The ProgressiVis system touches all the stages of the conceptual data analysis pipeline of fig:diagram; it integrates data management mechanisms, data analysis modules, as well as visualizations, perception, understanding, and decision making. Aviz will strengthen its work on the implementation of a natively progressive data science system. Such a system will lead to the following research topics:
- Progressive language kernel and data management mechanisms
- Progressive algorithms and computation strategies
- Progressive visualizations
- Management of uncertainties, computed from the algorithms and conveyed to the analysts.
A tutorial on the ProgressiVis toolkit was presented during the IEEE VIS 2025 Conference and was well attended. We are working toward enriching the toolkit so it can be applied for general analyses and visualizations in the forthcoming year. We also apply progressive visualization with the ParcoursVis tool, for the exploration of large scale medical patient patways, with millions of patients over a decade. ParcoursVis reaches an unmatched scalability due to its progressive rendering, allowing it to be applied to large scale medical datasets, at the regional and country level.
3.2 Research Axis 2: Physicality in Input and Output
Permanents involved: Petra Isenberg, Tobias Isenberg, Jean-Daniel Fekete




This is a compilation of images showing work the Aviz team did in the area of "physicality in input and output". The first image shows the Zooids project about miniature robots that can produce data physicalizations. The second shows a visualization for a smartwatch and fitness band about sleep data. The third shows situated visualizations in a video game. The third shows a visualization in augmented reality and a selection technique for choosing certain points.
During the last five years, we expanded our work on beyond-desktop environments for visualization. Our team has made contributions in the areas of data physicalization, visualization for wearable devices, situated and embedded visualization, and visualization in augmented reality.
Data Physicalization: Data physicalization is a rich and vast research area that studies the use of physical artifacts to convey data. It overlaps with a number of research areas including information/scientific visualization, visual analytics, tangible user interfaces, shape-changing interfaces, fabrication, as well as graphic design, architecture, and art. Physical data visualizations tap into our lifelong experience of perceiving and manipulating the physical world, either alone or with other people. Among the earliest man-made artifacts are physical representations of semantic concepts that provide physical metaphors that allow us to reason, remember, and communicate. With the advent of computers, we have substituted physical representations with pixels on a computer screen. The resurgence of physicalization as a research area, following our early definitions 58, asks what we have lost in this transformation. Certainly, a computer-based visualization allows us to zoom an image, transform variables in real time, and to zoom through virtual computer-based world. However, these representations can sever the relationship to the natural world, depriving us of the touch, feel, and emotion that comes from interacting with real objects. We studied several aspects of data physicalization including technical challenges of constructing physicalizations, potential benefits, and how historical examples could transfer to a modern world.
Visualization for Wearable and Mobile Devices: In the area of wearable and mobile-devices we engaged in device-driven research where we considered how small device form factors may influence how we need to design visualizations and how we can use them. Portable and wearable personal devices such as fitness tracking armbands, hand-held GPS trackers, smart watches, or mobile phones are very small displays that are capable of producing data themselves (through sensors), downloading it from other sources (through Wifi or Bluetooth), and displaying it immediately 61. Often the data is shown in the form of visualizations that have to be adapted to the small display size. We consider very small visualizations that are often used on such devices under the term “micro visualization” and have been working towards a better understanding of the complexities involved in designing and using micro visualizations but also studied the influence of the unique context of use of mobile devices on visualization use and design.
Situated and Embedded Data Representations: We study how embedding data visualizations in the context of the data sources can empower people to make effective use of their data in a variety of application contexts. Our goal in this work is to go beyond the traditional platforms of data analytics by using situated data visualizations on various types of non-traditional displays. In a situated data visualization, the data is directly visualized near the physical space, object, or person it originates from 80. For example, a person may attach small e-ink displays embedded with sensors at various locations of their house or their workplace, to better understand their use of space, of equipment, or of energy resources. Or a person who wishes to exercise more may use an augmented reality device to visualize their past running performance in-place. New situated data visualizations like these can surface information in the environment—allowing viewers to interpret data in-context and take action in response to it 81.
Visualization using Augmented Reality Devices: Many datasets are 3D-spatial in nature and researchers and practitioners could benefit from seeing them in true 3D space. This is where immersive technologies shine, and the recent advances in VR and AR headset technologies have made such displays accessible to the general public—the lack of large dedicated VR installations such as a CAVE is not preventing the use of immersive rendering anymore. Nonetheless, the investigation of 3D datasets also frequently requires researchers to use tools such as scripted analysis and statistical evaluation, and such direction of investigation will continue to be a cornerstone of scientific work. In our investigations we are thus interested in looking at, in particular, hybrid setups that allow researchers to use the best of both worlds: traditional workstations combined with an AR overlay for stereoscopic rendering of 3D data 78.
3.3 Research Axis 3: Perception, Cognition and Decision-Making
Permanents involved: Petra Isenberg, Tobias Isenberg, Jean-Daniel Fekete, Florent Cabric
As we collect increasingly large amounts of data in fields such as climate science, finance, and medicine, the need to understand and communicate that data becomes more important. Data visualizations are often used to give an overview of information, however it can be challenging to predict whether these visualizations will be effective before spending resources to develop them. Consequently, researchers make use of experimental methods from visual perception and cognition to study how we perceive and understand visualizations in order to develop generalized guidelines for optimizing effectiveness. On this research axis we have three focus areas:
Perception of Visualizations in Novel Contexts. Novel technology and usage contexts have several characteristics for data visualizations that warrant a (re-)evaluation of how well people can perceive visualizations. Characteristics we were particularly interested in include:
- Physical factors: Many now common displays have characteristics that warrant (re-)evaluation of what we know about visualizations to be displayed on them. Small form factors of displays such as smartwatches and fitness bands are an obvious characteristic. Some screens deviate from the standard rectangular form we are familiar with and use a circular geometry, which is another interesting design constraint for visualization.
- Data display mobility: Data display mobility captures the movement of the display(s) containing visual representations of data. Fixed, movable, carryable, wearable, and independently moving displays can be differentiated along this dimension. We conducted some of our research on carryable devices, including mobile devices such as smartphones and tablets but also wearable displays such as smartwatches and head-mounted displays.
- Context-of-use: Many novel displays are used in contexts that are much unlike traditional office settings. Visualizations here may be subjected to different lighting conditions and viewers may only afford very quick glances at the displays themselves. For example, when in a car the driver can only afford very quick glances at the GPS before returning to the primary task of arriving safely.
Within this focus area we worked on some of these aspects; such as the need for quick glances, the display size of visualizations, the movement of viewers or the data, and the understanding of 3D augmented reality spaces. We relied mostly on mixed-methods user studies where a quantitative analysis methodology was coupled with interviews or questionnaires.
Illustrative Visualization. This focus area takes inspiration from illustrators' decades to centuries of experience on perception and cognition to better portray scientific subject matter. Another input arises from the field of non-photorealistic rendering which has developed numerous techniques of stylizing images and other input data. Traditionally, illustrative visualization has thus been applied primarily to data with a concrete spatial mapping in 2D and, more frequently, in 3D space.
Another main direction of research in this context is what the role of abstraction is in illustrative visualization 77, 76 as well as visualization in general, and specifically how we can provide dedicated means to control the abstraction being applied to visual representations of data. This means that we need to go beyond seeing abstraction only as a side-product of stylization as it has traditionally been viewed in many approaches in non-photorealistic rendering as well as illustrative visualization to date, and investigate how we can interactively adjust it to provide practitioners with a means to find the best visual representations for a given task. For example, we have investigated this question in the context of structural biology 83 or DNA nanostructures 62, 63, 64 as well as the use of patterns as a visual variable for the representation of abstract data 55. We also want to expand this work to other application domains in the future.
Decision-Making with Visualizations. Human decision-making and cognitive biases are important research topics in the fields of psychology, economics and marketing. Visualization systems are increasingly used to support decision-making: large companies switch to visualization solutions to improve their decisions in a range of areas, where large sums of money or human lives are at stake. More and more, the ultimate goal of visualization is not to understand patterns in the data and get insights as was traditionally assumed, but to make good decisions. In order to fully understand how information visualizations can support decision-making, it is important to go beyond traditional evaluations based on data understanding, and study how visualizations interact with human judgment, human heuristics, and cognitive biases.
We pursue this important stream of research by investigating decision-making in the presence of uncertainty and incomplete information, in connection with the topics discussed in sec:progressive and the use of visualizations to support social choice and group decisions in the presence of conflicts of interest. How cognitive biases interact with visual perception is also an important and difficult question that has remained largely unexplored. More recently, we started a line of research on the visualization of values spanning multiple orders of magnitude that we call Order of Magnitude Values (OMVs) 1, 11, 32, 33. We designed novel visualizations to represent them, and study the cognitive support required to make sense of such numbers in the context of accounting.
3.4 Research Axis 4: Methodology for Visualization Research
Permanents involved: Petra Isenberg, Tobias Isenberg, Jean-Daniel Fekete
An important aspect of any scientific research is to establish and follow rigorous and effective methodologies for acquiring new knowledge. In the field of Visualization in particular, scientific discourse on the validity, use, and establishment of methodologies is important as the field is highly interdisciplinary, with diverse influences and opinions. It is important to establish, for example, what level of rigor the field should require of its methods, how to choose among established methods and methodologies, and how to best communicate the results of our empirical research. We focus our efforts on three main topics related to visualization research methodologies.
Promoting and Following Open Research Practices
For issues with open research practices to be addressed, educational materials and guidelines need to be written, so researchers have clarity about how to make their research more credible. Aviz members are working with the organizing bodies of the visualization research community to establish incentives for making research artifacts and potentially establish minimal requirements for openness in published articles. Meanwhile, it is important to continue measuring and cataloging openness in the field to monitor progress. The goal is to improve the credibility and applicability of the field’s research.
Shaping the Scientific Visualization Community Aviz researchers are heavily involved in the organization structure of IEEE visualization conferences, the most prestigious conference in our field, by proposing workshops, tutorials, serving on various organizing committees, steering committees, editorial boards. We, in particular, aid the process by providing data collection and analysis services through the vispubdata.org dataset that we are collecting, cleaning, and making available to the community. The dataset has already been used in research (e. g., 60) but also to shape the scientific community by proposing program committee members, new processes, and was used by the Visualization Restructuring Committee (ReVISe). We are also involved in the EuroVis community and participate at multiple levels to its organization and management.
3.5 Research Axis 5: Visualization Techniques
Permanents involved: Petra Isenberg, Tobias Isenberg, Jean-Daniel Fekete, Florent Cabric, Frederic Vernier
This image represents a new type of visualization to visualize dynamic hypergraphs.
We study several dedicated visualization approaches that intersect with our major goals above. One such set of approaches, particularly needed at the intersection of AR and VR, are those that fundamentally require both 3D and 2D representations: how to combine 3D representations with 2D representations, how both are linked with each other (initial work: 68), and how we need to design the interaction to most effectively and efficiently solve practical problems. The visualization field will benefit from a more fundamental and generalizable understanding of such hybrid 3D/2D environments. The individual research into the specific directions will provide a part of this understanding, but we also plan to arrive at a more theoretical understanding of this space. For this purpose we plan to formulate the properties of the respective components and their respective limitations and boundaries, how the individual components affect each other, and how the existing hybrid settings overcome the limitations and boundaries at the moment. Next, we aim to derive an interaction language to describe the current situation, to then be able to generalize the concepts to be able to inform the design of future interactive visualization systems.
We have also started to explore techniques to visualize dynamic hypergraphs 75 (see fig:ExamplesOfVisualizationTechniques) and their clustering 66. These dynamic hypergraphs are very effective at representing, e.g., people mentioned in documents across time, such as publications, contracts, personal records, etc. This new line of research is stirring interest in the visualization community but also in very different communities, such as social history, cybersecurity, health monitoring for bridges, and linguistics. We are now continuing to improve the visualization technique to better scale, and to support aggregation using interactive and automated techniques. Our technique for clustering social networks (social hypergraphs) based on ensemble clustering 66 is also applicable to other structures (simple graphs and tabular data). We want to generalize it and scale it to larger ensembles.
4 Application domains
4.1 Natural Sciences
We often deal with data that is inherently three-dimensional in nature, for example, from fields such as biology, astronomy, or medicine. We work with experts from the respective natural sciences to create, for example, illustrative visualizations of scientific data, such as a continuous zooming technique from the nucleus of a cell all the way down to the atom configuration of the DNA, for example, for the application in education. Also our work with immersive technology is often applied to application cases from the natural sciences.
4.2 Social Sciences
We collaborate with social science researchers from EHESS Paris on the visualization of dynamic networks; they use our systems (GeneaQuilts 49, Vistorian 69, PAOHVis 75, PK-Clustering 66) and teach them to students and researchers. Our tools are used daily by ethnographers and historians to study the evolution of social relations over time. In the social sciences, many datasets are gathered by individual researchers to answer a specific question, and automated analytical methods cannot be applied to these small datasets. Furthermore, the studies are often focused on specific persons or organizations and not always on the modeling or prediction of the behavior of large populations. The tools we design to visualize complex multivariate dynamic networks are unique and suited to typical research questions shared by a large number of researchers. This line of research was supported by the DataIA “HistorIA” project, and by the “IVAN” European project. We currently collaborate with PayAnalytics, an Icelandic company to visualize data to help companies close their gender pay gaps.
4.3 Medicine and Sports
We collaborate with the Health-Data-Hub on the analysis and visualization of French Social Security (CNAM) Data, patient pathways for various medical treatments, to help referent doctors and epidemiologists make sense of French health data. In particular, we are working on a subset of the CNAM Data focused on urinary problems, and we have received very positive feedback from doctors who can see what happens to the patients treated in France vs. what they thought happened through the literature. This project is getting a lot of traction from our partners in medicine, epidemiology, and the economy of health.
We are also collaborating with the “Assistance Publique - Hôpitaux de Paris” AP-HP with a funded project called URGE, aimed at improving the emergency services for the Parisian hospitals. See the press announcement.
We collaborate with multiple researchers on projects that apply visualizations to the sports and personal health context. Specifically, we are interested in providing effective visualizations for fitness trackers that are worn during sports activities. We have done extensive research on micro visualizations for smartwatches where we focused on how quickly people can retrieve information from their trackers. In addition, we have been working on embedding situated visualizations in sports videos to aid audiences but also athletes and coaches in associating data with the sports activity itself. The current ANR grant SportsViz will focus on this topic where we will also collaborate with French sports associations through our collaborators at Ecole Central de Lyon.

7 Latest software developments, platforms, open data
7.1 Latest software developments
7.1.1 ProgressiVis
-
Name:
progressive visualization and data analysis
-
Keywords:
Progressive visualization, Visualization, Visual analytics
-
Functional Description:
Instead of running algorithms to completion one after the other, as done in all existing scientific analysis systems, ProgressiVis modules run in short batches, each batch being only allowed to run for a specific quantum of time - typically 1 second - producing a usable result in the end, and yielding control to the next module. To perform the whole computation, ProgressiVis loops over the modules as many times as necessary to converge to a result that the analyst considers satisfactory.
ProgressiVis relies on well known Python libraries, such as numpy,scipy, Pandas, and Scikit-Learn.

7.1.2 Cartolabe
-
Name:
Cartolabe
-
Keyword:
Information visualization
-
Functional Description:
The goal of Cartolabe is to build a visual map representing the scientific activity of an institution/university/domain from published articles and reports. Using the HAL Database, Cartolabe provides the user with a map of the thematics, authors, and articles. ML techniques are used for dimensionality reduction, cluster, and topic identification, visualization techniques are used for a scalable 2D representation of the results.
Cartolabe has, in particular, been applied to the Grand Debat dataset (3M individual propositions from French Citizen, see https://cartolabe.fr/map/debat). The results were used to test both the scaling capabilities of Cartolabe and its flexibility to non-scientific and non-English corpora. We also added sub-map capabilities to display the result of a year/lab/word filtering as an online generated heatmap with only the filtered points to facilitate the exploration. Cartolabe has also been applied in 2020 to the COVID-19 Kaggle publication dataset (Cartolabe-COVID project) to explore these publications.

7.1.4 ParcoursVis
-
Name:
Visualization of Patient Pathways
-
Keywords:
Visualization, Health, Progressive visualization
-
Scientific Description:
We developed ParcoursVis, our Progressive Visual Analytics (PVA) tool to explore patients' care pathways at scale. Current tools to visualize temporal event sequences are restricted to datasets as large as a few thousand sequences to remain reactive. With ParcoursVis, we aim to visualize patients' care pathways stored in country-level databases, which can contain order of magnitudes higher of event sequences, at scale using a progressive architecture. PVA tools, instead of waiting for the whole computation to finish before rendering the final results, yield partial results each time the algorithm processes small chunks of data or iterations. This paradigm makes the tool reactive and quickens processes such as checking errors of a query.

Functional Description:
ParcoursVis allow extracting a subset of the nationwide database from CNAMTS, transforming the raw data into meaningful medical events, and visualizing it interactively at scale via a web interface.
For the moment, ParcoursVis focuses on non-cancerous prostate adenoma. With this focus, our domain expert users extract meaningful high-level types of events (e.g., treatments and outcomes) that the patients undertake in their care pathways.
Using a progressive visualization method, ParcoursVis visualizes in an aggregated manner the care pathways of tens of millions of patients treated with thousands of events over decades, several orders of magnitude more than existing interactive systems.

7.2 New platforms
7.2.1 Prepare the ProgressiVis Toolkit for a Wider Distribution
Participants: Jean-Daniel Fekete [correspondent], Christian Poli.
The ProgressiVis toolkit, implementing a Progressive Data Analysis and Visualization language and environment, has been under heavy development for many years. We have finished its packaging so it can be easily installed by partners who want to experiment with the toolkit and the concept it supports. A documentation is also available (in progress), as well as several graphical and interactive widgets to support its use in modern notebooks.
With the new book on Progressive Data Analysis published 53, we want to push the ProgressiVis toolkit as an advanced proof-of-concept of progressive system architecture.

8.1 Visualizing Orders of Magnitude Values
8.1.1 Lost in Magnitudes: Exploring Visualization Designs for Large Value Ranges
Participants: Katerina Batziakoudi [Berger-Levrault], Florent Cabric, Stéphanie Rey [Berger-Levrault], Jean-Daniel Fekete [correspondent].
The image shows our design space and the defined dimensions. Our design space encompasses three dimensions: MARKS (green), DATA (blue), and VISUAL CHANNELS (red). The image illustrates an example of using our design space as an interactive table, where a mark is selected, and visual channels are assigned to data attributes. Grey cells are invalid, according to the visualization literature. After checking for integrity constraints, a visualization is generated to perform the tasks.
We explore the design of visualizations for values spanning multiple orders of magnitude 1; we call them Orders of Magnitude Values (OMVs). Visualization researchers have shown that separating OMVs into two components, the mantissa and the exponent, and encoding them separately, overcomes limitations of linear and logarithmic scales. However, only a small number of such visualizations have been tested, and the design guidelines for visualizing the mantissa and exponent separately remain under-explored. To initiate this exploration, better understand the factors influencing the effectiveness of these visualizations, and create guidelines, we adopt a multi-stage workflow. We introduce a design space for visualizing mantissa and exponent, systematically generating and qualitatively evaluating all possible visualizations within it. From this evaluation, we derive guidelines. We select two visualizations that align with our guidelines and test them using a crowdsourcing experiment, showing they facilitate quantitative comparisons and increase confidence in interpretation compared to the state-of-the-art. Material and illustrations are available under CC-BY 4.0 at osf.io/uke76.
8.1.2 Beyond Log Scales: Toward Cognitively Informed Bar Charts for Orders of Magnitude Values
Participants: Katerina Batziakoudi [Berger-Levrault], Stéphanie Rey [Berger-Levrault], Jean-Daniel Fekete [correspondent].
Comparison of five bar charts showing order-of-magnitude differences in seven budget categories labeled A to G. Each chart maps categories on the x-axis and budget values in euros on the y-axis. The first chart uses a linear scale; smaller values are barely visible due to compression. The second uses a logarithmic scale; values are more readable but require multiple grid lines, and overlapping occurs in higher ranges. The third chart uses the EplusM scale, a piecewise linear scale where mantissas are interpolated linearly between logarithmically spaced exponents. The fourth chart, called Bricks, adds discrete stacked blocks to visually encode mantissa values. The fifth chart, Multi-Magnitude, introduces scale words like “millions” and “billions” by splitting the y-axis into separate faceted rows.
In this work, we challenge the dominant use of logarithmic scales to communicate values spanning multiple orders of magnitude to the general public. Focusing on bar charts, we incorporate cognitive insights into visualization design to better align with how humans perceive OMVs. Studies in cognitive psychology suggest that, for large numerical ranges such as millions and billions, people do not think logarithmically. Instead, they perceive numbers in a piecewise linear manner, grouping values into scale words (e.g., millions) and applying linear reasoning within each group. We build upon a recently introduced piecewise linear scale, EplusM, and validate its use in bar charts, which we refer to as EplusM bar charts. We also introduce two novel variants of the EplusM bar chart informed by findings in numerical perception: Bricks, which builds on the concepts of round numbers and subitizing, and Multi-Magnitude, which leverages categorical perception of large numbers. In a crowdsourced experiment, we evaluate four bar chart designs: 1) Log, 2) EplusM, 3) Bricks, and 4) Multi-Magnitude, across value retrieval and quantitative comparison tasks. Our results show that EplusM bar charts are significantly preferred over logarithmic designs, increase user confidence, and reduce perceived mental demand, while maintaining task performance. These findings suggest that EplusM bar charts can serve as effective alternatives to logarithmic ones when visualizing OMVs for general audiences.

8.2 Reframing Pattern: A Comprehensive Approach to a Composite Visual Variable
Participants: Tingying He [The University of Utah, Scientific Computing and Imaging Institute], Jason Dykes [City University, London], Petra Isenberg, Tobias Isenberg [correspondent].
Diagram of the process to generate a pattern. A pattern is described by three sets of pattern attributes: (1) the spatial arrangement of primitives, (2) the appearance relationships among primitives, and (3) the retinal visual variables applied to each individual primitive that define its appearance. We illustrate the attributes with pattern samples constructed both with a lattice and without one.
We present a new comprehensive theory for explaining, exploring, and using pattern as a visual variable in visualization. Although patterns have long been used for data encoding and continue to be valuable today, their conceptual foundations are precarious: the concepts and terminology used across the research literature and in practice is inconsistent, making it challenging to use patterns effectively and to conduct research to inform this widespread practice. To address this problem, we conduct a comprehensive cross-disciplinary literature review that clarifies ambiguities around the use of “pattern” and “texture”. As a result we offer a new consistent treatment of pattern as a composite visual variable composed of structured groups of graphic primitives that can serve as marks for encoding data individually and collectively. This new and widely applicable formulation opens a sizable design space for the visual variable pattern, which we formalize as a new pattern system characterized by three sets of variables: the spatial arrangement of primitives, the appearance relationships among primitives, and the retinal visual variables used on individual primitives. We show how our pattern system relates to existing visualization theory and highlight opportunities for visualization design. We further explore patterns based on complex spatial arrangements, demonstrating explanatory power and connecting our conceptualization to broader theory on maps and cartography.
8.3 Visualization in Motion
Participants: Lijie Yao [Xi’an Jiaotong-Liverpool University, correspondent], Federica Bucchieri [Université Paris-Saclay, CNRS, Inria, LISN], Victoria McArthur [Carleton University], Petra Isenberg, Anastasia Bezerianos [Université Paris-Saclay, CNRS, Inria, LISN].
We present a systematic review, an empirical study, and a first set of considerations for designing visualizations in motion, derived from a concrete scenario in which these visualizations were used to support a primary task. In practice, when viewers are confronted with embedded visualizations, they often have to focus on a primary task and can only quickly glance at a visualization showing rich, often dynamically updated, information. As such, the visualizations must be designed so as not to distract from the primary task, while at the same time being readable and useful for aiding the primary task. For example, in games, players who are engaged in a battle have to look at their enemies but also read the remaining health of their own game character from the health bar over their character’s head. Many trade-offs are possible in the design of embedded visualizations in such dynamic scenarios, which we explore in-depth in this paper with a focus on user experience. We use video games as an example of an application context with a rich existing set of visualizations in motion. We begin our work with a systematic review of in-game visualizations in motion. Next, we conduct an empirical user study to investigate how different embedded visualizations in motion designs impact user experience. We conclude with a set of considerations and trade-offs for designing visualizations in motion more broadly as derived from what we learned about video games.

Abstract:
The Ember project studies how situated data visualization systems can help people use their personal data (e.g., fitness and physiological data, energy consumption, banking transactions, online social activity,…) for their own benefit. Although personal data is generated in many areas of daily life, it remains underused by individuals. Rarely is personal data subjected to an in-depth analysis and used to inform daily decisions. This research aims to empower individuals to improve their lives by helping them become advanced consumers of their own data. This research builds on the area of personal visual analytics, which focuses on giving the general public effective and accessible tools to get insights from their own data. Personal visual analytics is a nascent area of research, but has so far focused on scenarios where the data visualization is far removed from the source of the data it refers to. The goal of this project is to address the limitations of traditional platforms of personal data analytics by exploring the potential of situated data visualizations. In a situated data visualization, the data is directly visualized near the physical space, object, or person it refers to. Situated data visualizations have many potential benefits: they can surface information in the physical environment and allow viewers to interpret data in-context; they can be tailored to highlight spatial connections between data and the physical environment, making it easier to make decisions and act on the physical world in response to the insights gained; and they can embed data into physical environments so that it remains visible over time, making it easier to monitor changes, observe patterns over time and collaborate with other people.
