      Kerracher, Natalie; Kennedy, Jessie (The Eurographics Association and John Wiley & Sons Ltd., 2017)
      Categorising tasks is a common pursuit in the visualisation research community, with a wide variety of taxonomies, typologies, design spaces, and frameworks having been developed over the last three decades. While these ...
    • CoreFlow: Extracting and Visualizing Branching Patterns from Event Sequences 

      Liu, Zhicheng; Kerr, Bernard; Dontcheva, Mira; Grover, Justin; Hoffman, Matthew; Wilson, Alan (The Eurographics Association and John Wiley & Sons Ltd., 2017)
      Event sequence datasets with high event cardinality and long sequences are difficult to visualize and analyze. In particular, it is hard to generate a high level visual summary of paths and volume of flow. Existing approaches ...
    • Cycle Plot Revisited: Multivariate Outlier Detection Using a Distance-Based Abstraction 

      Bögl, Markus; Filzmoser, Peter; Gschwandtner, Theresia; Lammarsch, Tim; Leite, Roger A.; Miksch, Silvia; Rind, Alexander (The Eurographics Association and John Wiley & Sons Ltd., 2017)
      The cycle plot is an established and effective visualization technique for identifying and comprehending patterns in periodic time series, like trends and seasonal cycles. It also allows to visually identify and contextualize ...
    • Dynamic Scene Graph: Enabling Scaling, Positioning, and Navigation in the Universe 

      Axelsson, Emil; Costa, Jonathas; Silva, Cláudio; Emmart, Carter; Bock, Alexander; Ynnerman, Anders (The Eurographics Association and John Wiley & Sons Ltd., 2017)
      In this work, we address the challenge of seamlessly visualizing astronomical data exhibiting huge scale differences in distance, size, and resolution. One of the difficulties is accurate, fast, and dynamic positioning and ...
    • Dynamic Visual Abstraction of Soccer Movement 

      Sacha, Dominik; Al-Masoudi, Feeras; Stein, Manuel; Schreck, Tobias; Keim, Daniel A.; Andrienko, Gennady; Janetzko, Halldór (The Eurographics Association and John Wiley & Sons Ltd., 2017)
      Trajectory-based visualization of coordinated movement data within a bounded area, such as player and ball movement within a soccer pitch, can easily result in visual crossings, overplotting, and clutter. Trajectory ...
    • An Empirical Study on the Reliability of Perceiving Correlation Indices using Scatterplots 

      Sher, Varshita; Bemis, Karen G.; Liccardi, Ilaria; Chen, Min (The Eurographics Association and John Wiley & Sons Ltd., 2017)
      Scatterplots have been in use for about two centuries, primarily for observing the relationship between two variables and commonly for supporting correlation analysis. In this paper, we report an empirical study that ...
    • Empirically Measuring Soft Knowledge in Visualization 

      Kijmongkolchai, Natchaya; Abdul-Rahman, Alfie; Chen, Min (The Eurographics Association and John Wiley & Sons Ltd., 2017)
      In this paper, we present an empirical study designed to evaluate the hypothesis that humans' soft knowledge can enhance the cost-benefit ratio of a visualization process by reducing the potential distortion. In particular, ...
