      Many datasets have multiple perspectives - for example space, time and description - and often analysts are required to study these multiple perspectives concurrently. This concurrent analysis becomes difficult when data ...
    • There is More to Streamgraphs than Movies: Better Aesthetics via Ordering and Lassoing 

      Bartolomeo, Marco Di; Hu, Yifan (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Streamgraphs were popularized in 2008 when The New York Times used them to visualize box office revenues for 7500 movies over 21 years. The aesthetics of a streamgraph is affected by three components: the ordering of the ...
    • PhysioEx: Visual Analysis of Physiological Event Streams 

      Kamaleswaran, Rishikesan; Collins, Christopher; James, Andrew; McGregor, Carolyn (The Eurographics Association and John Wiley & Sons Ltd., 2016)

    • Similarity Voting based Viewpoint Selection for Volumes 

      Tao, Yubo; Wang, Qirui; Chen, Wei; Wu, Yingcai; Lin, Hai (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Previous viewpoint selection methods in volume visualization are generally based on some deterministic measures of viewpoint quality. However, they may not express the familiarity and aesthetic sense of users for features ...
    • Designing Multiple Coordinated Visualizations for Tablets 

      Sadana, Ramik; Stasko, John (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      The use of multiple coordinated views (MCV) in data visualization provides analytic power because it allows a person to explore data under a variety of different perspectives. Since this design pattern utilizes multiple ...
    • Source Inversion by Forward Integration in Inertial Flows 

      Günther, Tobias; Theisel, Holger (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Inertial particles are finite-sized objects traveling with a certain velocity that differs from the underlying carrying flow, i.e., they are mass-dependent and subject to inertia. Their backward integration is in practice ...
    • Using Visualization to Explore Original and Anonymized LBSN Data 

      Tarameshloo, Ebrahim; Loorak, Mona Hosseinkhani; Fong, Philip W. L.; Carpendale, Sheelagh (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      We present GSUVis, a visualization tool designed to provide better understanding of location-based social network (LBSN) data. LBSN data is one of the most important sources of information for transportation, marketing, ...
    • Visual Analysis of Governing Topological Structures in Excitable Network Dynamics 

      Ngo, Quynh Quang; Hütt, Marc-Thorsten; Linsen, Lars (The Eurographics Association and John Wiley & Sons Ltd., 2016)
