    • Visualization-Aware Color Design 

      Szafir, Danielle Albers; Gleicher, Michael (The Eurographics Association, 2016)
      Color encoding design currently focuses on the colors themselves: visualization designers choose sets of colors that work well in isolation. However, the effectiveness of a color encoding depends on properties of the ...
    • Styrian Diversity Visualisation: Visualising Statistical Open Data with a LeanWeb App and Data Server 

      Andrews, Keith; Traunmüller, Thomas; Wolkinger, Thomas; Goldgruber, Eva; Gutounig, Robert; Ausserhofer, Julian (The Eurographics Association, 2016)
      Statistical open data is usually provided only in the form of spreadsheets or CSV files. The developers of open data apps must either restrict themselves to managable bite-sized chunks of data, which can be consumed (read, ...
    • TaCo: Comparative Visualization of Large Tabular Data 

      Hourieh, Reem; Stitz, Holger; Gehlenborg, Nils; Streit, Marc (The Eurographics Association, 2016)
      Tabular data plays a vital role in many different domains. In the course of a project, changes to the structure and content of tables can result in multiple instances of a table. A challenging task when working with such ...
    • Volume Rendering Using Principal Component Analysis 

      Alakkari, Salaheddin; Dingliana, John (The Eurographics Association, 2016)
      We investigate the use of Principal Component Analysis (PCA) for image-based volume rendering. We compute an eigenspace using training images, pre-rendered using a standard raycaster, from a spherically distributed range ...
    • Understanding Networks beyond Overlapping Clusters 

      Guchev, Vladimir; Angelini, S.; Amati, G. (The Eurographics Association, 2016)
      Tasks associated with the investigation of large complex clustered networks are widespread in various research areas. Among the popular and common approaches to exploratory analysis, it is definitely worthwhile to underscore ...
    • Tracking Space-Filling Features by Two-Step Optimization 

      Schnorr, Andrea; Freitag, Sebastian; Kuhlen, Torsten W.; Hentschel, Bernd (The Eurographics Association, 2016)
      We present a novel approach for tracking space-filling features, i.e., a set of features covering the entire domain. The assignment between successive time steps is determined by a two-step, global optimization scheme. ...
    • Visualizing Article Similarities in Wikipedia 

      Riehmann, Patrick; Potthast, Martin; Gruendl, Henning; Kiesel, Johannes; Jürges, Dean; Castiglia, Giuliano; Ter-Akopyan, Bagrat; Froehlich, Bernd (The Eurographics Association, 2016)
      In this poster we present intermediate results regarding visual text analytics on Wikipedia. We implemented a visualization providing insight about similarities among Wikipedia articles in terms of structure as well as ...
    • Towards Combining Attribute-based and Time Series-based Visual Querying 

      Sessler, David; Spott, Martin; Nauck, Detlef; Harmer, William; Kohlhammer, Jörn; Bernard, Jürgen (The Eurographics Association, 2016)
      We present a concept for the visual-interactive definition of meaningful subsets in data sets comprising multivariate attributes and time series data. Based on a generalization of requirements of a real-world user group, ...
    • Large-scale Argument Visualization (LSAV) 

      Khartabil, Dana; Wells, S.; Kennedy, Jessie (The Eurographics Association, 2016)
      Arguments are structures of premises and conclusions that underpin rational reasoning processes. Within complex knowledge domains, especially if they are contentious, argument structures can become large and complex. ...
    • Features vs Prototypes: Amplifying Cognition with Common Data Graphics 

      Migut, M. A.; Worring, M. (The Eurographics Association, 2016)
      The most common and important data visualizations, such as barcharts or scatterplots are typically feature-based. In this paper we question whether feature-based representations are favorable from the cognition point of ...
    • InVITe - Towards Intuitive Visualization of Iterations over Text 

      Lamqaddam, Houda; Aerts, Jan (The Eurographics Association, 2016)
      With InVITe, we are working towards intuitive visualization to support review of iterative modifications on text documents. In order to accomplish this, we perform simple matching of text snippets between the two versions ...
    • Geometry-Aware Visualization of Performance Data 

      Vierjahn, Tom; Hentschel, Bernd; Kuhlen, Torsten W. (The Eurographics Association, 2016)
      Phenomena in the performance behaviour of high-performance computing (HPC) applications can stem from the HPC system itself, from the application's code, but also from the simulation domain. In order to analyse the latter ...
    • Interactive Exploration of Student Generated Content presented in Blogs 

      Jusufi, Ilir; Milrad, Marcelo; Legaspi, Xurxo (The Eurographics Association, 2016)
      Nowadays blogs are regarded as tools for communication as well as an important source for spreading information in almost every subject. In recent years, school teachers have started to take advantage of this technology ...
    • Visual Analytics for Fraud Detection: Focusing on Profile Analysis 

      Leite, Roger Almeida; Gschwandtner, Theresia; Miksch, Silvia; Gstrein, Erich; Kuntner, Johannes (The Eurographics Association, 2016)
      Financial institutions are always interested in ensuring security and quality for their customers. Banks, for instance, need to identify and avoid harmful transactions. In order to detect fraudulent operations, data mining ...
    • Query by Visual Words: Visual Search for Scatter Plot Visualizations 

      Shao, Lin; Schleicher, Timo; Schreck, Tobias (The Eurographics Association, 2016)
      Finding interesting views in large collections of data visualizations, e.g., scatter plots, is challenging. Recently, ranking views based on heuristic quality measures has been proposed. However, quality measures may fail ...
    • Visual Analysis of Text Annotations for Stance Classification with ALVA 

      Kucher, Kostiantyn; Kerren, Andreas; Paradis, Carita; Sahlgren, Magnus (The Eurographics Association, 2016)
      The automatic detection and classification of stance taking in text data using natural language processing and machine learning methods create an opportunity to gain insight about the writers' feelings and attitudes towards ...
