      Spechtenhauser, Florian; Piringer, Harald (The Eurographics Association, 2018)
      Small-multiple displays are frequently used for visual comparison by juxtaposition. Explicitly encoding differences between cells enables to convey also minor differences in the data, but requires to specify references for ...
    • Pixel Wise Pie Charts: Placement of Data Points Visualizing Spatial Value Distributions 

      Janetzko, Halldor; Stein, Manuel (The Eurographics Association, 2018)
      Handling overplotted points in spatial pixel-based visualizations is usually done either by aggregation or sampling. The third rather unusual alternative is replacing data items untangling overplotted regions. Depending ...

      Angelini, Marco; Blasilli, Graziano; Lenti, Simone; Santucci, Giuseppe (The Eurographics Association, 2018)
      The evaluation of an information visualization system is a complex activity, involving the understanding of both the visualization itself and the process that it is meant to support. Moreover, if the evaluation activity ...
    • Exploring Interactive Linking Between Text and Visualization 

      Latif, Shahid; Liu, Diao; Beck, Fabian (The Eurographics Association, 2018)
      Visualizations are included in documents as augmentation to text and they become more intuitive if readers have the ability to interact with them. Modern web technologies facilitate the development of interactive documents ...

      Bernard, Jürgen; Hutter, Marco; Lehmann, Markus; Müller, Martin; Zeppelzauer, Matthias; Sedlmair, Michael (The Eurographics Association, 2018)
      An overarching goal of active learning strategies is to reduce the human effort when labeling datasets and training machine learning methods. In this work, we focus on the analysis of a (theoretical) quasi-optimal, ...
    • Using a Task Classification in the Visualisation Design Process for Task Understanding and Abstraction: an Empirical Study 

      Kerracher, Natalie; Kennedy, Jessie B.; Chalmers, Kevin (The Eurographics Association, 2018)
      Task classifications are widely purported to be useful in the design process, with various suggestions having been made for their use at the different stages. However, little has been written regarding the actual use of ...
    • Issues and Suggestions for the Development of a Biodiversity Data Visualization Support Tool 

      Kaur, Pawandeep; Klan, Friederike; König-Ries, Birgitta (The Eurographics Association, 2018)
      Visualizations are an important tool to transport information. However, finding the right visualization can be challenging. Using the biodiversity research domain as a showcase, we investigate where exactly these challenges ...
    • Sketching Temporal Uncertainty - An Exploratory User Study 

      Schwarzinger, Fabian; Roschal, Andreas; Gschwandtner, Theresia (The Eurographics Association, 2018)
      Real world datasets frequently contain inherent uncertainty of some kind. Most of the work in the context of visualizing temporal uncertainty, focus on evaluating and comparing different visualization approaches. This ...
    • VisGuides: A Forum for Discussing Visualization Guidelines 

      Diehl, Alexandra; Abdul-Rahman, Alfie; El-Assady, Mennatallah; Bach, Benjamin; Keim, Daniel; Chen, Min (The Eurographics Association, 2018)
      This paper presents VisGuides, a discussion platform to facilitate the collection, evaluation, critique, revision, and dissemination of visualization guidelines. As visualization becomes a more widespread discipline with ...
    • TapVis: A Data Visualization Approach for Assessment of Alternating Tapping Performance in Patients with Parkinson's Disease 

      Jusufi, Ilir; Memedi, Mevludin; Nyholm, Dag (The Eurographics Association, 2018)
      Advancements in telemedicine have been helpful for frequent monitoring of patients with Parkinson's disease (PD) from remote locations and assessment of their individual symptoms and treatment-related complications. These ...
    • ChemoExplorer: A Dashboard for the Visual Analysis of Chemotherapy Response in Breast Cancer Patients 

      Karall, Nikolaus; Gröller, Eduard; Raidou, Renata Georgia (The Eurographics Association, 2018)
