    • MVN-Reduce: Dimensionality Reduction for the Visual Analysis of Multivariate Networks 

      Martins, Rafael M.; Kruiger, J. F.; Minghim, Rosane; Telea, Alexandru C.; Kerren, Andreas (The Eurographics Association, 2017)
      The analysis of Multivariate Networks (MVNs) can be approached from two different perspectives: a multidimensional one, consisting of the nodes and their multiple attributes, or a relational one, consisting of the network's ...
    • In Situ and Post Processing Workflows for Asteroid Ablation Studies 

      Patchett, John M.; Nouanesengsy, Boonthanome; Gisler, Galen; Ahrens, James; Hagen, Hans (The Eurographics Association, 2017)
      Simulation scientists need to make decisions about what and how much output to produce. They must balance their ability to efficiently ingest the analysis with their ability to get more analysis. We study this balance as ...
    • TypoTweet Maps: Characterizing Urban Areas through Typographic Social Media Visualization 

      Godwin, Alex; Wang, Yongxin; Stasko, John T. (The Eurographics Association, 2017)
      Analyzing the important events and news stories that have captured the public interest in a city can be useful for determining the topics that are vital to the people that live there. Social media data, such as tweets, ...
    • An Argument Structure for Data Stories 

      Kosara, Robert (The Eurographics Association, 2017)
      Many data stories in journalism do not have a story arc, but rather present facts without much structure. This mirrors the popular inverted pyramid style of writing that presents the most important information up front, ...
    • Nodes, Paths, and Edges: Using Mental Maps to Augment Crime Data Analysis in Urban Spaces 

      Godwin, Alex; Stasko, John T. (The Eurographics Association, 2017)
      Citizen participation can provide valuable insight into data that is not captured by official sources. In this paper, we propose a technique for using mental maps consisting of three fundamental elements: nodes, paths, and ...
    • Marching Pentatopes for Continuous Morphing of Isosurfaces From Four Dimensional Data in HTML5/WebGL 

      Watters, Aaron R. (The Eurographics Association, 2017)
      Animations which show three dimensional volumes continuously changing over time facilitate the exploration and analysis of complex data sets such as calcium image data of neural activity and phase contrast magnetic resonance ...
    • Spatiotemporal Visualization of Gene Expression in the Developing Mouse Brain 

      Li, Qihang; Huang, Kun; Machiraju, Raghu (The Eurographics Association, 2017)
      Exploring and visualizing the spatiotemporal fold change of gene expression is an increasingly important challenge especially in structures as the developing brain. Focusing on the Allen Developing Mouse Brain data, we ...
    • PubViz: Lightweight Visual Presentation of Publication Data 

      Rind, Alexander; Haberson, Andrea; Blumenstein, Kerstin; Niederer, Christina; Wagner, Markus; Aigner, Wolfgang (The Eurographics Association, 2017)
      Publications play a central role in presenting the outcome of scientific research but are typically presented as textual lists, whereas related work in visualization of publication focuses on exploration - not presentation. ...
    • Dynamic Label Placement for Forensic Case Visualization 

      Sirk, Christof; Kalkofen, Denis; Schmalstieg, Dieter; Bornik, Alexander (The Eurographics Association, 2017)
      Forensic case analysis and in court presentation requires comprehensible illustrations and animations of findings and their relations to the course of events. Often this can only be achieved by adding textual descriptions. ...
    • On Establishing Visualization Requirements: A Case Study in Product Costing 

      Vosough, Zana; Groh, Rainer; Schulz, Hans-Jörg (The Eurographics Association, 2017)
      The process of identifying visualization requirements is an important part of every visualization researcher's and practitioner's job. Nevertheless, the scientific literature is rather sparse on this topic, usually resorting ...
    • Interactive Level-of-Detail Visualization of 3D-Polarized Light Imaging Data Using Spherical Harmonics 

      Hänel, Claudia; Demiralp, Ali C.; Axer, Markus; Grässel, David; Hentschel, Bernd; Kuhlen, Torsten W. (The Eurographics Association, 2017)
      3D-Polarized Light Imaging (3D-PLI) provides data that enables an exploration of brain fibers at very high resolution. However, the visualization poses several challenges. Beside the huge data set sizes, users have to ...
    • Reflections on an Experiment, Evaluating the Impact of Spatialisation on Exploration 

      Roux, Clement; McAuley, John (The Eurographics Association, 2017)
      This paper reports on an experiment designed to evaluate whether visualising a digital library (using a spatialisation technique) can influence exploratory search behaviour. In the experiment we asked participants to ...
    • Readability and Precision in Pictorial Bar Charts 

      Skau, Drew; Kosara, Robert (The Eurographics Association, 2017)
      Bar charts embellished with unique artistic styles, or made to look like real objects, are common in information graphics. Embellishments are typically considered detrimental to readability and accuracy, since they add ...
    • Hybrid-Treemap Layouting 

      Hahn, Sebastian; Döllner, Jürgen (The Eurographics Association, 2017)
      This paper presents an approach for hybrid treemaps, which applies and combines several different layout principles within a single tree map in contrast to traditional treemap variants based on a single layout concept. To ...
