ALT Screenshot of a new, open source, web-based, geospatial visualization tool, Exploropleth, that lets users interact with a catalog of established data binning methods, and subsequently compare, customize, and export custom maps. The screenshot shows small multiples of 16 choropleth maps, each showing the same Life Expectancy data for U.S. counties, but using distinct binning methods, e.g., Natural Breaks, Pretty Breaks, Standard Deviation, and so on.
ALT Figure 5. Combine View lets users analyze a) a combination of one or more binning methods by visualizing b) the most consistent Bin, c) the frequency of the most consistent Bin, and d) both together for each U.S. county in separate choropleths. The new, resiliency binning method then utilizes this information to g) determine “resilient” bins (counts, intervals) that are also visualized in a choropleth. Hovering any county on the map shows a tooltip with relevant information about the county, as shown in e) and f).
