      Cognitive biases are systematic errors in judgment due to an over-reliance on rule-of-thumb heuristics. Recent research suggests that cognitive biases, like numerical anchoring, transfers to visual analytics in the form ...
    • Segmentifier: Interactive Refinement of Clickstream Data 

      Dextras-Romagnino, Kimberly; Munzner, Tamara (The Eurographics Association and John Wiley & Sons Ltd., 2019)
      Clickstream data has the potential to provide insights into e-commerce consumer behavior, but previous techniques fall short of handling the scale and complexity of real-world datasets because they require relatively clean ...

      Angelini, Marco; Buchmüller, Juri; Keim, Daniel A.; Meschenmoser, Philipp; Santucci, Giuseppe (The Eurographics Association and John Wiley & Sons Ltd., 2019)
      Visualizing contextual information to a map often comes at the expense of overplotting issues. Especially for use cases with relevant map features in the immediate vicinity of an information to add, occlusion of the relevant ...
    • A Visual Tool for the Analysis of Algorithms for Tomographic Fiber Reconstruction in Materials Science 

      Fröhler, Bernhard; Elberfeld, Tim; Möller, Torsten; Hege, Hans-Christian; Weissenböck, Johannes; De Beenhouwer, Jan; Sijbers, Jan; Kastner, Johann; Heinzl, Christoph (The Eurographics Association and John Wiley & Sons Ltd., 2019)
      We present visual analysis methods for the evaluation of tomographic fiber reconstruction algorithms by means of analysis, visual debugging and comparison of reconstructed fibers in materials science. The methods are ...
    • Visualizing for the Non-Visual: Enabling the Visually Impaired to Use Visualization 

      Choi, Jinho; Jung, Sanghun; Park, Deok Gun; Choo, Jaegul; Elmqvist, Niklas (The Eurographics Association and John Wiley & Sons Ltd., 2019)
      The majority of visualizations on the web are still stored as raster images, making them inaccessible to visually impaired users. We propose a deep-neural-network-based approach that automatically recognizes key elements ...
    • ClustMe: A Visual Quality Measure for Ranking Monochrome Scatterplots based on Cluster Patterns 

      Abbas, Mostafa M.; Aupetit, Michaël; Sedlmair, Michael; Bensmail, Halima (The Eurographics Association and John Wiley & Sons Ltd., 2019)
      We propose ClustMe, a new visual quality measure to rank monochrome scatterplots based on cluster patterns. ClustMe is based on data collected from a human-subjects study, in which 34 participants judged synthetically ...
    • A Stable Graph Layout Algorithm for Processes 

      Mennens, Robin; Scheepens, Roeland; Westenberg, Michel (The Eurographics Association and John Wiley & Sons Ltd., 2019)
      Process mining enables organizations to analyze data about their (business) processes. Visualization is key to gaining insight into these processes and the associated data. Process visualization requires a high-quality ...
    • Visualization Support for Developing a Matrix Calculus Algorithm: A Case Study 

      Giesen, Joachim; Klaus, Julien; Laue, Sören; Schreck, Ferdinand (The Eurographics Association and John Wiley & Sons Ltd., 2019)
      The development of custom interactive visualization tools for specific domains and applications has been made much simpler recently by a surge of visualization tools, libraries and frameworks. Most of these tools are ...

    • Designing Animated Transitions to Convey Aggregate Operations 

      Kim, Younghoon; Correll, Michael; Heer, Jeffrey (The Eurographics Association and John Wiley & Sons Ltd., 2019)
      Data can be aggregated in many ways before being visualized in charts, profoundly affecting what a chart conveys. Despite this importance, the type of aggregation is often communicated only via axis titles. In this paper, ...
