IGM-Vis: Analyzing Intergalactic and Circumgalactic Medium Absorption Using Quasar Sightlines in a Cosmic Web Context
(The Eurographics Association and John Wiley & Sons Ltd., 2019)We introduce IGM-Vis, a novel astrophysics visualization and data analysis application for investigating galaxies and the gas that surrounds them in context with their larger scale environment, the Cosmic Web. Environment ... -
InsideInsights: Integrating Data-Driven Reporting in Collaborative Visual Analytics
(The Eurographics Association and John Wiley & Sons Ltd., 2019)Analyzing complex data is a non-linear process that alternates between identifying discrete facts and developing overall assessments and conclusions. In addition, data analysis rarely occurs in solitude; multiple collaborators ... -
Interactive Visualization of Flood and Heavy Rain Simulations
(The Eurographics Association and John Wiley & Sons Ltd., 2019)In this paper, we present a real-time technique to visualize large-scale adaptive height fields with C1-continuous surface reconstruction. Grid-based shallow water simulation is an indispensable tool for interactive flood ... -
An Interactive Visualization System for Large Sets of Phase Space Trajectories
(The Eurographics Association and John Wiley & Sons Ltd., 2019)We introduce a visual analysis system with GPU acceleration techniques for large sets of trajectories from complex dynamical systems. The approach is based on an interactive Boolean combination of subsets into a Focus+Context ... -
Interactive Volumetric Visual Analysis of Glycogen-derived Energy Absorption in Nanometric Brain Structures
(The Eurographics Association and John Wiley & Sons Ltd., 2019)Digital acquisition and processing techniques are changing the way neuroscience investigation is carried out. Emerging applications range from statistical analysis on image stacks to complex connectomics visual analysis ... -
Investigating Effects of Visual Anchors on Decision-Making about Misinformation
(The Eurographics Association and John Wiley & Sons Ltd., 2019)Cognitive biases are systematic errors in judgment due to an over-reliance on rule-of-thumb heuristics. Recent research suggests that cognitive biases, like numerical anchoring, transfers to visual analytics in the form ... -
Investigating the Manual View Specification and Visualization by Demonstration Paradigms for Visualization Construction
(The Eurographics Association and John Wiley & Sons Ltd., 2019)Abstract Interactivity plays an important role in data visualization. Therefore, understanding how people create visualizations given different interaction paradigms provides empirical evidence to inform interaction design. ... -
Kyrix: Interactive Pan/Zoom Visualizations at Scale
(The Eurographics Association and John Wiley & Sons Ltd., 2019)Pan and zoom are basic yet powerful interaction techniques for exploring large datasets. However, existing zoomable UI toolkits such as Pad++ and ZVTM do not provide the backend database support and data-driven primitives ... -
Latent Space Cartography: Visual Analysis of Vector Space Embeddings
(The Eurographics Association and John Wiley & Sons Ltd., 2019)Latent spaces-reduced-dimensionality vector space embeddings of data, fit via machine learning-have been shown to capture interesting semantic properties and support data analysis and synthesis within a domain. Interpretation ... -
Linking and Layout: Exploring the Integration of Text and Visualization in Storytelling
(The Eurographics Association and John Wiley & Sons Ltd., 2019)Modern web technologies are enabling authors to create various forms of text visualization integration for storytelling. This integration may shape the stories' flow and thereby affect the reading experience. In this paper, ... -
Multiple Views: Different Meanings and Collocated Words
(The Eurographics Association and John Wiley & Sons Ltd., 2019)We report on an in-depth corpus linguistic study on 'multiple views' terminology and word collocation. We take a broad interpretation of these terms, and explore the meaning and diversity of their use in visualisation ... -
netflower: Dynamic Network Visualization for Data Journalists
(The Eurographics Association and John Wiley & Sons Ltd., 2019)Journalists need visual interfaces that cater to the exploratory nature of their investigative activities. In this paper, we report on a four-year design study with data journalists. The main result is netflower, a visual ... -
An Ontological Framework for Supporting the Design and Evaluation of Visual Analytics Systems
(The Eurographics Association and John Wiley & Sons Ltd., 2019)Designing, evaluating, and improving visual analytics (VA) systems is a primary area of activities in our discipline. In this paper, we present an ontological framework for recording and categorizing technical shortcomings ... -
Optimizing Stepwise Animation in Dynamic Set Diagrams
(The Eurographics Association and John Wiley & Sons Ltd., 2019)A set diagram represents the membership relation among data elements. It is often visualized as secondary information on top of primary information, such as the spatial positions of elements on maps and charts. Visualizing ... -
Oui! Outlier Interpretation on Multi-dimensional Data via Visual Analytics
(The Eurographics Association and John Wiley & Sons Ltd., 2019)Outliers, the data instances that do not conform with normal patterns in a dataset, are widely studied in various domains, such as cybersecurity, social analysis, and public health. By detecting and analyzing outliers, ... -
A Random Sampling O(n) Force-calculation Algorithm for Graph Layouts
(The Eurographics Association and John Wiley & Sons Ltd., 2019)This paper proposes a linear-time repulsive-force-calculation algorithm with sub-linear auxiliary space requirements, achieving an asymptotic improvement over the Barnes-Hut and Fast Multipole Method force-calculation ... -
