Small Multiples (juxtapose location) Single Map (juxtapose time) Cartogram (visual encodings use map features) Proportional Symbol Map (visual encodings use symbols on top of map features) GlyphSM DorlingSM Barchart1M (a) (b) (c) Fig. 1. The three visualizations compared in our study. (a) Dorling cartograms as small multiples, (b) proportional symbols (circles) on maps as small multiples, and (c) proportional symbols (bar charts) on a single map. In this example, each map shows the values of two artificially-created variables over four years. In each case, both variables have an overall positive correlation (Pearson correlation coefficient ≥ 0.75) and no monotonic evolution.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
