    • Visualizing Expanded Query Results 

      Mazurek, Michael; Waldner, Manuela (The Eurographics Association and John Wiley & Sons Ltd., 2018)
      When performing queries in web search engines, users often face difficulties choosing appropriate query terms. Search engines therefore usually suggest a list of expanded versions of the user query to disambiguate it or ...
    • Design Factors for Summary Visualization in Visual Analytics 

      Sarikaya, Alper; Gleicher, Michael; Szafir, Danielle Albers (The Eurographics Association and John Wiley & Sons Ltd., 2018)
      Data summarization allows analysts to explore datasets that may be too complex or too large to visualize in detail. Designers face a number of design and implementation choices when using summarization in visual analytics ...
    • Bladder Runner: Visual Analytics for the Exploration of RT-Induced Bladder Toxicity in a Cohort Study 

      Raidou, Renata Georgia; Casares-Magaz, Oscar; Amirkhanov, Aleksandr; Moiseenko, Vitali; Muren, Ludvig P.; Einck, John P.; Vilanova, Anna; Gröller, Eduard (The Eurographics Association and John Wiley & Sons Ltd., 2018)

      Embedding and visualizing large-scale high-dimensional data in a two-dimensional space is an important problem, because such visualization can reveal deep insights of complex data. However, most of the existing embedding ...
    • Assessing Effects of Task and Data Distribution on the Effectiveness of Visual Encodings 

      Kim, Younghoon; Heer, Jeffrey (The Eurographics Association and John Wiley & Sons Ltd., 2018)
      In addition to the choice of visual encodings, the effectiveness of a data visualization may vary with the analytical task being performed and the distribution of data values. To better assess these effects and create ...
    • SetCoLa: High-Level Constraints for Graph Layout 

      Hoffswell, Jane; Borning, Alan; Heer, Jeffrey (The Eurographics Association and John Wiley & Sons Ltd., 2018)
