      Animated visualizations are one of the methods for finding and understanding complex structures of time-dependent vector fields. Many visualization designs can be used to this end, such as streamlines, vector glyphs, and ...
    • A Globally Conforming Lattice Structure for 2D Stress Tensor Visualization 

      Wang, Junpeng; Wu, Jun; Westermann, Rüdiger (The Eurographics Association and John Wiley & Sons Ltd., 2020)
      We present a visualization technique for 2D stress tensor fields based on the construction of a globally conforming lattice. Conformity ensures that the lattice edges follow the principal stress directions and the aspect ...
    • PAVED: Pareto Front Visualization for Engineering Design 

      Cibulski, Lena; Mitterhofer, Hubert; May, Thorsten; Kohlhammer, Jörn (The Eurographics Association and John Wiley & Sons Ltd., 2020)
      Design problems in engineering typically involve a large solution space and several potentially conflicting criteria. Selecting a compromise solution is often supported by optimization algorithms that compute hundreds of ...
    • Set Streams: Visual Exploration of Dynamic Overlapping Sets 

      Agarwal, Shivam; Beck, Fabian (The Eurographics Association and John Wiley & Sons Ltd., 2020)
      In many applications, membership of set elements changes over time. Since each element can be present in multiple sets, the sets also overlap. As a result, it becomes challenging to visualize the temporal change in set ...
    • Quantitative Comparison of Time-Dependent Treemaps 

      Vernier, Eduardo; Sondag, Max; Comba, João; Speckmann, Bettina; Telea, Alexandru; Verbeek, Kevin (The Eurographics Association and John Wiley & Sons Ltd., 2020)
      Rectangular treemaps are often the method of choice to visualize large hierarchical datasets. Nowadays such datasets are available over time, hence there is a need for (a) treemaps that can handle time-dependent data, and ...
    • Augmenting Node-Link Diagrams with Topographic Attribute Maps 

      Preiner, Reinhold; Schmidt, Johanna; Krösl, Katharina; Schreck, Tobias; Mistelbauer, Gabriel (The Eurographics Association and John Wiley & Sons Ltd., 2020)
      We propose a novel visualization technique for graphs that are attributed with scalar data. In many scenarios, these attributes (e.g., birth date in a family network) provide ambient context information for the graph ...
    • Metro Maps on Octilinear Grid Graphs 

      Bast, Hannah; Brosi, Patrick; Storandt, Sabine (The Eurographics Association and John Wiley & Sons Ltd., 2020)
      Schematic transit maps (often called "metro maps" in the literature) are important to produce comprehensible visualizations of complex public transit networks. In this work, we investigate the problem of automatically ...
    • Fuzzy Contour Trees: Alignment and Joint Layout of Multiple Contour Trees 

      Lohfink, Anna-Pia; Wetzels, Florian; Lukasczyk, Jonas; Weber, Gunther H.; Garth, Christoph (The Eurographics Association and John Wiley & Sons Ltd., 2020)
      We describe a novel technique for the simultaneous visualization of multiple scalar fields, e.g. representing the members of an ensemble, based on their contour trees. Using tree alignments, a graph-theoretic concept similar ...
