      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. ...
    • Enhancing Scatterplots with Multi-Dimensional Focal Blur 

      Staib, Joachim; Grottel, Sebastian; Gumhold, Stefan (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Scatterplots directly depict two dimensions of multi-dimensional data points, discarding all other information. To visualize all data, these plots are extended to scatterplot matrices, which distribute the information of ...
    • 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 ...
    • Hierarchical Stochastic Neighbor Embedding
