    • Phase Space Projection of Dynamical Systems 

      Bartolovic, Nemanja; Gross, Markus; Günther, Tobias (The Eurographics Association and John Wiley & Sons Ltd., 2020)
      Dynamical systems are commonly used to describe the state of time-dependent systems. In many engineering and control problems, the state space is high-dimensional making it difficult to analyze and visualize the behavior ...
    • 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 ...
    • Quantitative Evaluation of Time-Dependent Multidimensional Projection Techniques
