    Additional On-Demand Dimension for Data Visualization
    (The Eurographics Association, 2017) Hube, Natalie; Müller, Mathias; Groh, Rainer; Barbora Kozlikova and Tobias Schreck and Thomas Wischgoll
    In this paper, we present a concept to interactively extend an 2d visualization by an additional on-demand dimension. We use categorical data in a multidimensional information space applied in a travel search scenario. Parallel sets are used as the basis for the visualization concept, since this is particularly suitable for the visualization of categorical data. The on-demand dimension expands the vertical axis of a parallel coordinate graph into depth axis and is intended to increase comparability of path variables with respect to the number of elements belonging to the respective parameter axis instead of direct comparability of individual paths and keep relations between the parallel sets. The presented implementation suits as foundation for further studies about the usefulness of a dynamic, on demand extension a of 2d visualizations into spatial visualizations. Furthermore, we present some additional approaches about the usage of the increased visualization space.

    PubViz: Lightweight Visual Presentation of Publication Data
    (The Eurographics Association, 2017) Rind, Alexander; Haberson, Andrea; Blumenstein, Kerstin; Niederer, Christina; Wagner, Markus; Aigner, Wolfgang; Barbora Kozlikova and Tobias Schreck and Thomas Wischgoll
    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. To bridge this gap, we conducted a design study of an interactive visual representation of publication data in a BibTeX file. This paper reports our domain and problem characterization as well as our visualization design decisions in light of our user-centered design process including interviews, two user studies with a paper prototype and a d3.js prototype, and practical application at our group's website.

    TExVis: An Interactive Visual Tool to Explore Twitter Data
    (The Eurographics Association, 2017) Humayoun, Shah Rukh; Ardalan, Saman; AlTarawneh, Ragaad; Ebert, Achim; Barbora Kozlikova and Tobias Schreck and Thomas Wischgoll
    Exploring tweets enables us understanding people's reaction and feedback regarding any particular event or product. Many tools have been developed to visualize Twitter data based on some criteria, e.g., keyword frequency or evolution of topics. Visualizing the relations between the keywords of the underlying Twitter data opens another window to analyze the people's reaction towards a particular event/product. Targeting this concern, our developed tool, called TExVis (Tweets Explorer and Visualizer), visualizes important keywords (e.g., hashtags, nouns, verbs) from the underlying tweets based on their frequency and shows the relations between them based on some criteria (e.g., the common tweets), using an extended Chord diagram. TExVis also visualizes the sentimental polarity for a better understanding of the keywords associated tweets. Further, the provided interaction, multi-level navigation, and filtering options help the users in better exploration of the underlying tweets. A user study with 16 participants shows a high acceptance towards the tool and our approach in general.
