      Santala, Simo; Oulasvirta, Antti; Weinkauf, Tino (The Eurographics Association, 2020)
      The design space of scatterplots consists of a number of parameters such as marker size and shape, image width and aspect ratio, and opacity. Different parameters yield different visual impressions of the scatterplot. ...
    • Width-Scale Bar Charts for Data with Large Value Range 

      Höhn, Markus; Wunderlich, Marcel; Ballweg, Kathrin; Landesberger, Tatiana von (The Eurographics Association, 2020)
      Data sets with large value range are difficult to visualize with traditional linear bar charts. Usually, a logarithmic scale is used in these cases. However, the logarithmic scale suffers from non-linearity. Recently, ...
    • TopoLines: Topological Smoothing for Line Charts 

      Rosen, Paul; Suh, Ashley; Salgado, Christopher; Hajij, Mustafa (The Eurographics Association, 2020)
      Line charts are commonly used to visualize a series of data values. When the data are noisy, smoothing is applied to make the signal more apparent. Conventional methods used to smooth line charts, e.g., using subsampling ...
    • Evaluating Strategies of Exploratory Visual Data Analysis in Multi Device Environments 

      Alsaiari, Abeer; Aurisano, Jillian; Johnson, Andrew E. (The Eurographics Association, 2020)
      Supporting exploratory visual data analysis is essential when multiple analysts collaborate using multiple devices. Yet, we still have no full understanding of how the iterative process of analysis unfolds in complex ...
    • Influence of Container Resolutions on the Layout Stability of Squarified and Slice-And-Dice Treemaps 

      Knauthe, Volker; Ballweg, Kathrin; Wunderlich, Marcel; Landesberger, Tatiana von; Guthe, Stefan (The Eurographics Association, 2020)
      In this paper, we analyze the layout stability for the squarify and slice-and-dice treemap layout algorithms when changing the visualization containers resolution. We also explore how rescaling a finished layout to another ...
    • Investigating the Role of Locus of Control in Moderating Complex Analytic Workflows 

      Crouser, R. Jordan; Ottley, Alvitta; Swanson, Kendra; Montoly, Ananda (The Eurographics Association, 2020)
      Throughout the last decade, researchers have shown that the effectiveness of a visualization tool depends on the experience, personality, and cognitive abilities of the user. This work has also demonstrated that these ...
    • Characterizing Exploratory Behaviors on a Personal Visualization Interface Using Interaction Logs 

      Sukumar, Poorna Talkad; Martinez, Gonzalo J.; Grover, Ted; Mark, Gloria; D'Mello, Sidney K.; Chawla, Nitesh V.; Mattingly, Stephen M.; Striegel, Aaron D. (The Eurographics Association, 2020)
      Personal visualizations present a separate class of visualizations where users interact with their own data to draw inferences about themselves. In this paper, we study how a realistic understanding of personal visualizations ...
    • Exploring Design Opportunities for Visually Congruent Proxemics in Information Visualization: A Design Space 

      Chulpongsatorn, Neil; Yu, Jackie; Knudsen, Søren (The Eurographics Association, 2020)
      We explore design opportunities for varying visual complexity of information visualizations based on distance. Through considering visual congruency and proxemics interaction, we describe a design space that considers ...
    • Examining Design-Centric Test Participants in Graphical Perception Experiments 

      Guo, Grace; Dy, Bianchi; Ibrahim, Nazim; Joyce, Sam Conrad; Poorthuis, Ate (The Eurographics Association, 2020)
      In this paper, we replicate a foundational study in graphical perception, and compare our findings from using design-centric participants with that of previous studies. We also assess the visual accuracy of two groups, ...
    • Task-based Colormap Design Supporting Visual Comprehension in Process Tomography 

      Zhang, Yuchong; Fjeld, Morten; Said, Alan; Fratarcangeli, Marco (The Eurographics Association, 2020)
      Color coding is a fundamental technique for mapping data to visual representations, allowing people to carry out comprehension-based tasks. Process tomography is a rapidly developing non-invasive imaging technique used in ...
    • Interactive Creation of Perceptually Uniform Color Maps 

      Lambers, Martin (The Eurographics Association, 2020)
      A large number of design rules have been identified for color maps used in Scientific Visualization. One of the most important of these is perceptual uniformity, which at the same time is one of the hardest to guarantee ...
    • Designing Pairs of Colormaps for Visualizing Bivariate Scalar Fields 

      Ware, Colin; Samsel, Francesca; Rogers, David H.; Navratil, Paul; Mohammed, Ayat (The Eurographics Association, 2020)
      In scientific visualization there is sometimes a requirement for two colormaps to be used to represent two co-registered scalar fields. One solution is to represent one of the fields as a continuous colormapped image, and ...
    • Dissecting Visual Analytics: Comparing Frameworks for Interpreting and Modelling Observed Visual Analytics Behavior 

      Brown, Vanessa; Turkay, Cagatay; Jianu, Radu (The Eurographics Association, 2020)
