      Cartograms visualize quantitative data about a set of regions such as countries or states. There are several different types of cartograms and - for some - algorithms to automatically construct them exist. We focus on ...
    • A Multi-task Comparative Study on Scatter Plots and Parallel Coordinates Plots 

      Kanjanabose, Rassadarie; Abdul-Rahman, Alfie; Chen, Min (The Eurographics Association and John Wiley & Sons Ltd., 2015)
      Previous empirical studies for comparing parallel coordinates plots and scatter plots showed some uncertainty about their relative merits. Some of these studies focused on the task of value retrieval, where visualization ...

      Aboulhassan, Amal; Baum, Daniel; Wodo, Olga; Ganapathysubramanian, Baskar; Amassian, Aram; Hadwiger, Markus (The Eurographics Association and John Wiley & Sons Ltd., 2015)
      Current characterization methods of the so-called Bulk Heterojunction (BHJ), which is the main material of Organic Photovoltaic (OPV) solar cells, are limited to the analysis of global fabrication parameters. This reduces ...
    • Perfopticon: Visual Query Analysis for Distributed Databases 

      Moritz, Dominik; Halperin, Daniel; Howe, Bill; Heer, Jeffrey (The Eurographics Association and John Wiley & Sons Ltd., 2015)
      Distributed database performance is often unpredictable due to issues such as system complexity, network congestion, or imbalanced data distribution. These issues are difficult for users to assess in part due to the opaque ...
    • Persistent Homology for the Evaluation of Dimensionality Reduction Schemes 

      Rieck, Bastian; Leitte, Heike (The Eurographics Association and John Wiley & Sons Ltd., 2015)
      High-dimensional data sets are a prevalent occurrence in many application domains. This data is commonly visualized using dimensionality reduction (DR) methods. DR methods provide e.g. a two-dimensional embedding of the ...
    • Photoelasticity Raycasting 

      Bußler, Michael; Ertl, Thomas; Sadlo, Filip (The Eurographics Association and John Wiley & Sons Ltd., 2015)
      We present a novel physically-based method to visualize stress tensor fields. By incorporating photoelasticity into traditional raycasting and extending it with reflection and refraction, taking into account polarization, ...
    • Quantitative Measures for Cartogram Generation Techniques 

      Alam, Md. Jawaherul; Kobourov, Stephen G.; Veeramoni, Sankar (The Eurographics Association and John Wiley & Sons Ltd., 2015)
      Cartograms are used to visualize geographically distributed data by scaling the regions of a map (e.g., US states) such that their areas are proportional to some data associated with them (e.g., population). Thus the ...
    • Rationale Visualization for Safety and Security 

      Scheepens, Roeland; Michels, Steffen; Wetering, Huub van de; Wijk, Jarke J. van (The Eurographics Association and John Wiley & Sons Ltd., 2015)
