• Task Taxonomy for Cartograms 

  Nusrat, Sabrina; Kobourov, Stephen (The Eurographics Association, 2015)

  Cartograms are maps in which areas of geographic regions (countries, states) appear in proportion to some variable of interest (population, income). Despite the popularity of cartograms and the large number of cartogram ...

• A Testbed Combining Visual Perception Models for Geographic Gaze Contingent Displays 

  Bektas, Kenan; Cöltekin, Arzu; Krüger, Jens; Duchowski, Andrew T. (The Eurographics Association, 2015)
