      Zhang, Zhuohao; Malik, Sana; Guo, Shunan; Hoffswell, Jane; Rossi, Ryan; Du, Fan; Koh, Eunyee (The Eurographics Association, 2022)
      Business analysts often create static, data-driven reports to summarize and communicate findings from marketing dashboards. However, the requirements and workflow for creating data-driven reports in business analytics have ...
    • Understanding the Role and Value of Interaction: First Steps 

      Aigner, W. (The Eurographics Association, 2011)
      Visual Analytics strongly emphasizes the importance of interaction. However, until now, interaction is only sparingly treated as subject matter on its own. How and why interactivity is beneficial to gain insight and make ...
    • A Unified Process for Visual-Interactive Labeling 

      Bernard, Jürgen; Zeppelzauer, Matthias; Sedlmair, Michael; Aigner, Wolfgang (The Eurographics Association, 2017)
      Assigning labels to data instances is a prerequisite for many machine learning tasks. Similarly, labeling is applied in visualinteractive analysis approaches. However, the strategies for creating labels often differ in the ...
    • The Use of High-Dimensional Visualizations in Explaining Hospital Pricing Patterns 

      Perkins, Miriam; Grinstein, Georges (The Eurographics Association, 2015)
      The Centers for Medicare and Medicaid Services (CMS) has made public a data set showing what hospitals charged and what Medicare paid for the one hundred most common inpatient stays. By law payments approximate a hospital's ...
    • Utilizing Treemaps for Multicriterial Search of 3D Objects 

      Petkos, Georgios; Darlagiannis, Vasilios; Moustakas, Konstantinos; Tzovaras, Dimitrios (The Eurographics Association, 2010)

    • Visual Analysis for Hospital Infection Control using a RNN Model 

      Müller, Martin; Petzold, Markus; Wunderlich, Marcel; Baumgartl, Tom; Höhn, Markus; Eichel, Vanessa; Mutters, Nico T.; Scheithauer, Simone; Marschollek, Michael; Landesberger, Tatiana von (The Eurographics Association, 2020)
      Bacteria and viruses are transmitted among patients in the hospital. Infection control experts develop strategies for infection control. Currently, this is done mostly manually, which is time-consuming and error-prone. ...
    • Visual Analysis of Advanced Manufacturing Simulations 

      Wörner, M.; Ertl, T. (The Eurographics Association, 2011)
      Today's manufacturing companies are faced with requests for highly customer-specific products that come in numerous variants but small numbers of units per variant. Therefore, their manufacturing processes need to be ...
