    • Visualizing Co-occurrence of Events in Populations of Viral Genome Sequences 

      Sarikaya, Alper; Correll, Michael; Dinis, Jorge M.; O'Connor, David H.; Gleicher, Michael (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Virologists are not only interested in point mutations in a genome, but also in relationships between mutations. In this work, we present a design study to support the discovery of correlated mutation events (called ...
    • Glyphs for Asymmetric Second-Order 2D Tensors 

      Seltzer, Nicholas; Kindlmann, Gordon (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Tensors model a wide range of physical phenomena. While symmetric tensors are sufficient for some applications (such as diffusion), asymmetric tensors are required, for example, to describe differential properties of fluid ...
    • How Ordered Is It? On the Perceptual Orderability of Visual Channels 

      Chung, David H. S.; Archambault, Daniel; Borgo, Rita; Edwards, Darren J.; Laramee, Robert S.; Chen, Min (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      The design of effective glyphs for visualisation involves a number of different visual encodings. Since spatial position is usually already specified in advance, we must rely on other visual channels to convey additional ...
    • Arcs, Angles, or Areas: Individual Data Encodings in Pie and Donut Charts 

      Skau, Drew; Kosara, Robert (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Pie and donut charts have been a hotly debated topic in the visualization community for some time now. Even though pie charts have been around for over 200 years, our understanding of the perceptual factors used to read ...
    • Comparing Bar Chart Authoring with Microsoft Excel and Tangible Tiles 

      Wun, Tiffany; Payne, Jennifer; Huron, Samuel; Carpendale, Sheelagh (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Providing tools that make visualization authoring accessible to visualization non-experts is a major research challenge. Currently the most common approach to generating a visualization is to use software that quickly and ...
    • Space-Time Bifurcation Lines for Extraction of 2D Lagrangian Coherent Structures 

      Machado, Gustavo Mello; Boblest, Sebastian; Ertl, Thomas; Sadlo, Filip (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      We present a novel and efficient technique to extract Lagrangian coherent structures in two-dimensional time-dependent vector fields. We show that this can be achieved by employing bifurcation line extraction in the ...
    • Visualizing the Impact of Geographical Variations on Multivariate Clustering 

      Zhang, Yifan; Luo, Wei; Mack, Elizabeth A.; Maciejewski, Ross (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Traditional multivariate clustering approaches are common in many geovisualization applications. These algorithms are used to define geodemographic profiles, ecosystems and various other land use patterns that are based ...
    • Exploring and Comparing Clusterings of Multivariate Data Sets Using Persistent Homology 

      Rieck, Bastian; Leitte, Heike (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Clustering algorithms support exploratory data analysis by grouping inputs that share similar features. Especially the clustering of unlabelled data is said to be a fiendishly difficult problem, because users not only have ...
    • Pathfinder: Visual Analysis of Paths in Graphs 

      Partl, Christian; Gratzl, Samuel; Streit, Marc; Wassermann, Anne-Mai; Pfister, Hanspeter; Schmalstieg, Dieter; Lex, Alexander (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      The analysis of paths in graphs is highly relevant in many domains. Typically, path-related tasks are performed in node-link layouts. Unfortunately, graph layouts often do not scale to the size of many real world networks. ...
    • TimeArcs: Visualizing Fluctuations in Dynamic Networks 

      Dang, Tuan Nhon; Pendar, Nick; Forbes, Angus G. (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      In this paper we introduce TimeArcs, a novel visualization technique for representing dynamic relationships between entities in a network. Force-directed layouts provide a way to highlight related entities by positioning ...
    • Interactive 3D Force-Directed Edge Bundling 

      Zielasko, Daniel; Weyers, Benjamin; Hentschel, Bernd; Kuhlen, Torsten W. (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Interactive analysis of 3D relational data is challenging. A common way of representing such data are node-link diagrams as they support analysts in achieving a mental model of the data. However, naïve 3D depictions of ...
    • Comparing Node-Link and Node-Link-Group Visualizations From An Enjoyment Perspective 

      Saket, Bahador; Scheidegger, Carlos; Kobourov, Stephen (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      While evaluation studies in visualization often involve traditional performance measurements, there has been a concerted effort to move beyond time and accuracy. Of these alternative aspects, memorability and recall of ...
    • Exploring Items and Features with IF,FI-Tables 

      Corput, Paul van der; Wijk, Jarke J. van (The Eurographics Association and John Wiley & Sons Ltd., 2016)
