    • Pathfinder: Visual Analysis of Paths in Graphs 

      Partl, Christian; Gratzl, Samuel; Streit, Marc; Wassermann, Anne-Mai; Pfister, Hanspeter; Schmalstieg, Dieter; Lex, Alexander (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      The analysis of paths in graphs is highly relevant in many domains. Typically, path-related tasks are performed in node-link layouts. Unfortunately, graph layouts often do not scale to the size of many real world networks. ...
    • Exploring Items and Features with IF,FI-Tables 

      Corput, Paul van der; Wijk, Jarke J. van (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      The exploration of high-dimensional data is challenging because humans have difficulty to understand more than three dimensions. We present a new visualization concept that enables users to explore such data and, specifically, ...
    • Comparing Node-Link and Node-Link-Group Visualizations From An Enjoyment Perspective 

      Saket, Bahador; Scheidegger, Carlos; Kobourov, Stephen (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      While evaluation studies in visualization often involve traditional performance measurements, there has been a concerted effort to move beyond time and accuracy. Of these alternative aspects, memorability and recall of ...
    • TimeArcs: Visualizing Fluctuations in Dynamic Networks 

      Dang, Tuan Nhon; Pendar, Nick; Forbes, Angus G. (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      In this paper we introduce TimeArcs, a novel visualization technique for representing dynamic relationships between entities in a network. Force-directed layouts provide a way to highlight related entities by positioning ...
    • Interactive 3D Force-Directed Edge Bundling 

      Zielasko, Daniel; Weyers, Benjamin; Hentschel, Bernd; Kuhlen, Torsten W. (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Interactive analysis of 3D relational data is challenging. A common way of representing such data are node-link diagrams as they support analysts in achieving a mental model of the data. However, naïve 3D depictions of ...
    • Visualizing the Impact of Geographical Variations on Multivariate Clustering 

      Zhang, Yifan; Luo, Wei; Mack, Elizabeth A.; Maciejewski, Ross (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Traditional multivariate clustering approaches are common in many geovisualization applications. These algorithms are used to define geodemographic profiles, ecosystems and various other land use patterns that are based ...
    • Space-Time Bifurcation Lines for Extraction of 2D Lagrangian Coherent Structures 

      Machado, Gustavo Mello; Boblest, Sebastian; Ertl, Thomas; Sadlo, Filip (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      We present a novel and efficient technique to extract Lagrangian coherent structures in two-dimensional time-dependent vector fields. We show that this can be achieved by employing bifurcation line extraction in the ...
    • Comparing Bar Chart Authoring with Microsoft Excel and Tangible Tiles 

      Wun, Tiffany; Payne, Jennifer; Huron, Samuel; Carpendale, Sheelagh (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Providing tools that make visualization authoring accessible to visualization non-experts is a major research challenge. Currently the most common approach to generating a visualization is to use software that quickly and ...
    • Visual Analysis of Tumor Control Models for Prediction of Radiotherapy Response 

      Raidou, Renata Georgia; Casares-Magaz, Oscar; Muren, Ludvig Paul; Heide, Uulke A. van der; Rørvik, Jarle; Breeuwer, Marcel; Vilanova, Anna (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      In radiotherapy, tumors are irradiated with a high dose, while surrounding healthy tissues are spared. To quantify the probability that a tumor is effectively treated with a given dose, statistical models were built and ...
    • AVOCADO: Visualization of Workflow-Derived Data Provenance for Reproducible Biomedical Research 

      Stitz, Holger; Luger, Stefan; Streit, Marc; Gehlenborg, Nils (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      A major challenge in data-driven biomedical research lies in the collection and representation of data provenance information to ensure that findings are reproducibile. In order to communicate and reproduce multi-step ...
    • MCFTLE: Monte Carlo Rendering of Finite-Time Lyapunov Exponent Fields 

      Günther, Tobias; Kuhn, Alexander; Theisel, Holger (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Traditionally, Lagrangian fields such as finite-time Lyapunov exponents (FTLE) are precomputed on a discrete grid and are ray casted afterwards. This, however, introduces both grid discretization errors and sampling errors ...
    • From Visual Exploration to Storytelling and Back Again 

      Gratzl, Samuel; Lex, Alexander; Gehlenborg, Nils; Cosgrove, Nicola; Streit, Marc (The Eurographics Association and John Wiley & Sons Ltd., 2016)
