    • The Impact of Distribution and Chart Type on Part-to-Whole Comparisons 

      Kosara, Robert (The Eurographics Association, 2019)
      Pie charts and treemaps are commonly used in business settings to show part-to-whole relationships. In a study, we compare pie charts, treemaps, stacked bars, and two circular charts when answering part-to-whole questions ...
    • Defining an Analysis: A Study of Client-Facing Data Scientists 

      Mosca, Abigail; Robinson, Shannon; Clarke, Meredith; Redelmeier, Rebecca; Coates, Sebastian; Cashman, Dylan; Chang, Remco (The Eurographics Association, 2019)
      As the sophistication of data analyses increases many subject matter experts looking to make data-driven decisions turn to data scientists to help with their data analysis needs. These subject matter experts may have little ...
    • A Construction Kit for Visual Exploration Interfaces 

      Keck, Mandy; Groh, Rainer (The Eurographics Association, 2019)
      With a continuously increasing amount of data and resources on the internet and in large document collections, effective visual exploration interfaces are becoming more and more important. In recent years, many novel ...
    • Online Learning of Visualization Preferences through Dueling Bandits for Enhancing Visualization Recommendations 

      Kassel, Jan-Frederik; Rohs, Michael (The Eurographics Association, 2019)
      A visualization recommender supports the user through automatic visualization generation. While previous contributions primarily concentrated on integrating visualization design knowledge either explicitly or implicitly, ...
    • WordStream: Interactive Visualization for Topic Evolution 

      Dang, Tommy; Nguyen, Huyen N.; Pham, Vung (The Eurographics Association, 2019)
      This paper introduces WordStream, an interactive visual tool for the demonstration of topic evolution. Our approach utilizes the two popular techniques. Word clouds are designed to give an engaging visualization of text ...
    • The Design Space of SparkWords 

      Brath, Richard; MacMurchy, Peter; Banissi, Ebad (The Eurographics Association, 2019)
      The design space of SparkWords is consistently-sized words; embedded in sequential text (e.g. prose, lists); embellished by adding data, including categoric, ordered or quantitative data, that is encoded by a variety of ...
    • MOOCad: Visual Analysis of Anomalous Learning Activities in Massive Open Online Courses 

      Mu, Xing; Xu, Ke; Chen, Qing; Du, Fan; Wang, Yun; Qu, Huamin (The Eurographics Association, 2019)
      The research on Massive Open Online Course (MOOC) has mushroomed worldwide due to the technical revolution and its unprecedented enrollments. Existing work mainly focuses on performance prediction, content recommendation, ...
    • Label Placement for Outliers in Scatterplots 

      Mumtaz, Haris; Garderen, Mereke van; Beck, Fabian; Weiskopf, Daniel (The Eurographics Association, 2019)
      In many application scenarios, outliers can be associated with specific importance for various reasons. In such cases, labeling outliers is important to connect them to the actual semantics of the respective entity. In ...
    • Simulation and Visualization of Fluid Flows Around Real Objects in Augmented Reality 

      Tian, Xingze; Günther, Tobias (The Eurographics Association, 2019)
      The long-term vision of augmented reality is to seamlessly integrate digital content into the real world, which provides new means to make physical processes visible that are usually invisible to the naked eye. One such ...
    • Objective Finite-Time Saddles and their Connection to FTLE 

      Bujack, Roxana; Dutta, Soumya; Rojo, Irene Baeza; Zhang, Duan; Günther, Tobias (The Eurographics Association, 2019)
      Based on an intuitive physical definition of what a finite-time saddle-like behavior is, we derive a mathematical definition. We show that this definition builds the link between two FTLE-based saddle generalizations, which ...
    • Visualizing Transportation Flows with Mode Split using Glyphs 

      Pérez-Messina, Ignacio; Graells-Garrido, Eduardo (The Eurographics Association, 2019)
      The increasing trend of using unconventional data in urban planning environments has led to the need for developing systems that can visualize this data. Here we present a visualization for studying commuting flows within ...
    • Color Names Across Languages: Salient Colors and Term Translation in Multilingual Color Naming Models 

      Kim, Younghoon; Thayer, Kyle; Gorsky, Gabriella Silva; Heer, Jeffrey (The Eurographics Association, 2019)
      Color names facilitate the identification and communication of colors, but may vary across languages. We contribute a set of human color name judgments across 14 common written languages and build probabilistic models that ...
    • Viz-Blocks: Building Visualizations and Documents in the Browser 

      McNeill, Graham; Hale, Scott A. (The Eurographics Association, 2019)
      Viz-Blocks is a simple browser-based UI for data exploration and document creation. It incorporates the Vega-Lite grammar of graphics for standard visualizations (including multiple views and interaction) whereas 'code ...
    • ReLVis: Visual Analytics for Situational Awareness During Reinforcement Learning Experimentation 

      Saldanha, Emily; Praggastis, Brenda; Billow, Todd; Arendt, Dustin L. (The Eurographics Association, 2019)
      Reinforcement learning (RL) is a branch of machine learning where an agent learns to maximize reward through trial and error. RL is challenging and data/compute intensive leading practitioners to become overwhelmed and ...
    • CoCoa: A Linked Network Visualization System of Co-citation and Co-author Relationships 

      Nakazawa, Rina; Itoh, Takayuki; Saito, Takafumi (The Eurographics Association, 2019)
