Item EuroVis 2024 Panels and Tutorials: Frontmatter(The Eurographics Association, 2024) Schulz, Hans-Jörg; Isenberg, Tobias; Schulz, Hans-Jörg; Isenberg, TobiasItem EuroVis 2025 Panels and Tutorials: Frontmatter(The Eurographics Association, 2025) Isenberg, Tobias; Sedlmair, Michael; Tierny, Julien; Isenberg, Tobias; Sedlmair, Michael; Tierny, JulienItem Future Challenges and Unsolved Problems in Health Visualization(The Eurographics Association, 2025) Bernard, Jürgen; Borland, David; Laramee, Robert S.; Preim, Bernard; Raidou, Renata G.; Vilanova Bartroli, Anna; Isenberg, Tobias; Sedlmair, Michael; Tierny, JulienWith the growing popularity of wearable devices, health-related sensors, electronic health records (EHR), population health records (PopHR), computational biology and simulation, imaging data such as CT and MRI scans, and X-rays, the volume of digital health data is growing rapidly. Large volumes of heterogeneous health data require advanced visualization and visual analytics systems to uncover valuable insight buried in complex sources of data. As a rapidly evolving sub-field of visualization and visual analytics, many interactive health visualization systems have been proposed, developed, and evaluated by clinicians to support effective clinical analysis and decision making. Despite the growing progress in the field, many challenges and unsolved problems remain. The health-related problems that we face today are a clear sign of the growing need to progress in this area. This panel presents an open discussion of the top future challenges and unsolved problems in health and healthrelated visualization. The panel features experts with a range of different backgrounds covering a variety of health-related perspectives. This panel provides a valuable overview of health-related visualization revealing both mature areas and future research directions.Item The Future of Interactive Data Analysis and Visualization(The Eurographics Association, 2023) Bernard, Jürgen; El-Assady, Mennatallah; Hotz, Ingrid; Schulz, H.-J.The interactive data analysis and visualization (VIS) community has prospered for over thirty years. Generation after generation, the community has evolved its understanding of research problems and, along the way, contributed various techniques, applications, and research methods. While some of the developed techniques have stood the test of time, we will consider what else needs to be remembered or even revitalized from the good old days in this panel. Further, VIS is currently facing exciting times, with great changes and trends within and outside the community. Thus, in this panel, we want to analyze current research trends and discuss our most exciting ideas and directions. Looking ahead, it can already be anticipated that the future of VIS is subject to change. In this panel, we want to map out future research directions for our community. Along these three lines, the guiding theme of our interactive panel will be three types of (provoking) statements: (i) In the good old days, I liked when we did . . . (ii) Currently, a most exciting trend is ... and (iii) In the future, we will be doing . . . Come and join us to reflect on past and present trends, daring a look ahead to an exciting future for the interactive data analysis and visualization community!Item Integrating Sonification and Visualization - But Why?(The Eurographics Association, 2024) Rind, Alexander; Enge, Kajetan; Iber, Michael; Rönnberg, Niklas; Lenzi, Sara; Elmquist, Elias; Caiola, Valentina; Lan, Fangfei; Höldrich, Robert; Aigner, Wolfgang; Schulz, Hans-Jörg; Isenberg, TobiasThe research communities studying visualization and sonification share exceptionally similar goals, essentially aiming to make data interpretable to humans. One community uses visual representations, while the other employs auditory (nonspeech) representations of data. Although the two communities have much in common, they developed mostly in parallel, with only comparatively few examples of integrated audiovisual data analysis idioms presented so far. This panel brings together researchers from both the fields of visualization and sonification to collectively discuss the question: 'Integrating Sonification and Visualization - but why?' In the panel discussion, we will tackle this question along two main hypotheses: Combining the modalities to (1) increase the ''bandwidth from data to brain,'' or (2) to increase a user's personal engagement during the data analysis process. On the one hand, designers might aim to communicate more data in less time or gain more and more complex insights from the data by using a multi-modal display. This argument follows an understanding that two senses should be capable of processing more information than ''just'' one. On the other hand, sometimes, a more engaged analysis of the represented data is desirable. Engagement with data visualization stands as a crucial topic in numerous contexts within our field, encouraging ''deeper'' thinking by expert analysts, readers of data journalism articles, and students in educational settings. We hypothesize that integrating visualization with sonification holds the potential to enhance user engagement during analysis. Through the panel discussion, we want to delve into the spectrum between aiming for bandwidth and engagement, seeking to understand the opportunities and challenges of integrating sonification and visualization.Item Panel Proposal: What is the Role of Workshops in Visualization Research?(The Eurographics Association, 2025) Gillmann, Christina; Reina, Guido; Schmidt, Johanna; Wiegreffe, Daniel; Isenberg, Tobias; Sedlmair, Michael; Tierny, JulienWorkshops are a core component of EuroVis and VIS conferences, providing a dedicated space for presenting innovative research, discussing new findings, and fostering community connections. Despite consistent interest in attendance, recent years have seen a troubling decline in workshop submissions, particularly since the COVID-19 pandemic. We propose a panel to explore workshops' role within the VIS community, examining factors that contribute to their success and sustainability. Key questions include identifying the elements that make workshops appealing to participants and submitters, understanding their impact on scientific careers, and assessing the potential for workshops to evolve or be integrated into larger conference formats. The goal of the panel is to develop a position paper summarizing insights from these discussions to help shape the future of workshops in the visualization and Visual Analytics field.Item Reliable Visual Analytics with Dimensionality Reduction: Quality Evaluation and Interpretation of Projections(The Eurographics Association, 2025) Jeon, Hyeon; Fujiwara, Takanori; Martins, Rafael M.; Isenberg, Tobias; Sedlmair, Michael; Tierny, JulienDimensionality reduction (DR) is widely used for visual analytics, but the insights obtained from these visualizations may often be unreliable. For example, DR projections distort the intrinsic structure of high-dimensional data in ways that may not be obvious at first glance, potentially leading analysts to inaccurate interpretations. Even reliable visual patterns may be hard to interpret regarding what exactly they convey about the underlying data, due to the often severe compression from hundreds (or thousands) of dimensions down to the visual space. In this tutorial, we discuss how to enhance the reliability of visual analytics with DR by focusing on two perspectives: quality evaluations and interpretations. While the former helps users identify or create projections with fewer distortions, the latter provides a reliable method for deriving insights from those projections. By combining lecture and coding exercises, we expect our tutorial to provide a grounded basis for audiences to use DR in a more reliable mannerItem Running Online User Studies with the reVISit Framework(The Eurographics Association, 2025) Wilburn, Jack; Shrestha, Hilson; Cutler, Zach; Ding, Yiren; He, Tingying; McNutt, Andrew M.; Harrison, Lane; Lex, Alexander; Isenberg, Tobias; Sedlmair, Michael; Tierny, JulienThere currently are two main approaches for running online user studies: experimenters can use commercial survey tools, which are easy to use but can be costly, hamper reproducibility, and have limitations for complex stimuli; or they can build custom software to run and instrument a study, which is a laborious and complex task. In this tutorial, we introduce participants to a new, open-source alternative: the reVISit study platform. Many studies quickly reach a level of complexity such that designers have not only to consider their stimuli and experimental tasks, but also the study UI, data hosting, participant recruiting, randomization, etc. ReVISit ameliorates these problems and allows study designers to focus more on the research questions and stimulus design. ReVISit removes the tedium of study design by providing built-in components that most studies will need. ReVISit uses a domain specific language to allow study designers to quickly create studies, and to deploy them as static websites that are publicly accessible. This tutorial will introduce reVISit to the visualization community and allow community members to get hands on experience with it through a series of practical examples. Throughout the tutorial, participants will improve on a study until they have developed and deployed a study of an interactive, fully instrumented data visualization.
