Evaluating Cartogram Effectiveness [article]

Sabrina Nusrat, Md. Jawaherul Alam, Stephen G. Kobourov
2017 arXiv   pre-print
Based on a recent task taxonomy for cartograms, we evaluate four major different types of cartograms: contiguous, non-contiguous, rectangular, and Dorling cartograms.  ...  Despite the popularity of cartograms and the large number of cartogram types, there are few studies evaluating the effectiveness of cartograms in conveying information.  ...  Dorling cartograms are used in the UK Guardian newspaper [6] to visualize social structure and in the New York Times to show the distribution of medals in Olympic Games since 2008 [8] .  ...
