    • Characterizing Exploratory Visual Analysis: A Literature Review and Evaluation of Analytic Provenance in Tableau 

      Battle, Leilani; Heer, Jeffrey (The Eurographics Association and John Wiley & Sons Ltd., 2019)
      Supporting exploratory visual analysis (EVA) is a central goal of visualization research, and yet our understanding of the process is arguably vague and piecemeal. We contribute a consistent definition of EVA through review ...

      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 ...
    • CV3: Visual Exploration, Assessment, and Comparison of CVs 

      Filipov, Velitchko; Arleo, Alessio; Federico, Paolo; Miksch, Silvia (The Eurographics Association and John Wiley & Sons Ltd., 2019)
      The Curriculum Vitae (CV, also referred to as ''résumé'') is an established representation of a person's academic and professional history. A typical CV is comprised of multiple sections associated with spatio-temporal, ...
    • The Dependent Vectors Operator 

      Hofmann, Lutz; Sadlo, Filip (The Eurographics Association and John Wiley & Sons Ltd., 2019)
      In this paper, we generalize the parallel vectors operator due to Peikert and Roth to arbitrary dimension, i.e., to four-dimensional fields and beyond. Whereas the original operator tested for parallelism of two (derived) ...
    • 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, ...
    • DIVA: Exploration and Validation of Hypothesized Drug-Drug Interactions 

      Kakar, Tabassum; Qin, Xiao; Rundensteiner, Elke A.; Harrison, Lane; Sahoo, Sanjay K.; De, Suranjan (The Eurographics Association and John Wiley & Sons Ltd., 2019)
      Adverse reactions caused by drug-drug interactions are a major public health concern. Currently, adverse reaction signals are detected through a tedious manual process in which drug safety analysts review a large number ...
    • Efficient Optimal Overlap Removal: Algorithms and Experiments 

      Meulemans, Wouter (The Eurographics Association and John Wiley & Sons Ltd., 2019)
      Motivated by visualizing spatial data using proportional symbols, we study the following problem: given a set of overlapping squares of varying sizes, minimally displace the squares as to remove the overlap while maintaining ...
    • EuroVis 2019 CGF 38-3: Frontmatter 

      Gleicher, Michael; Viola, Ivan; Leitte, Heike (The Eurographics Association and John Wiley & Sons Ltd., 2019)
    • Evaluating Image Quality Measures to Assess the Impact of Lossy Data Compression Applied to Climate Simulation Data 

      Baker, Allison; Hammerling, Dorit; Turton, Terece (The Eurographics Association and John Wiley & Sons Ltd., 2019)
      Applying lossy data compression to climate model output is an attractive means of reducing the enormous volumes of data generated by climate models. However, because lossy data compression does not exactly preserve the ...
    • Examining Implicit Discretization in Spectral Schemes 

      Quinan, P. Samuel; Padilla, Lace M. K.; Creem-Regehr, Sarah H.; Meyer, Miriah (The Eurographics Association and John Wiley & Sons Ltd., 2019)
      Two of the primary reasons rainbow color maps are considered ineffective trace back to the idea that they implicitly discretize encoded data into hue-based bands, yet no research addresses what this discretization looks ...
    • An Exploratory User Study of Visual Causality Analysis 

      Yen, Chi-Hsien Eric; Parameswaran, Aditya; Fu, Wai-Tat (The Eurographics Association and John Wiley & Sons Ltd., 2019)
