Dynamic queries and brushing on choropleth maps

By Gunjan Dang, Chris North and Ben Shneiderman


Users who must combine dcmographic, economic or other data in a geographic context are ofren hampered by the integration of tabular and nwp representations. Static, paper-based solutions limit the amount of data that can be placed on a single map or table. By providing an effective user interface, we believe that researchers, journalists, teachers, and students can explore complex data sets more rapidly and effectively. This paper presents Dynamaps, a generalized map-based informalion-visualization tool for dynamic queries and brushing on choropleth maps. Users can use color-coding to show a variable on each geographic region, and then filler out areas that do not meet the desired criteria. In addition, a scatterplot view and a details-on-demand window support overviews and specific fact-finding
