Non-Contiguous Cartogram

Full Screen

Unlike choropleth maps, cartograms encode data using area rather than color, resulting in distorted geographic boundaries. In this example, states are shown as circles centered arond their geographic position. The size of the circle is based on teh 2015 GDP as reported on Wikipedia.

This is forked from mbostock‘s block: Non-Contiguous Cartogram. The original was inspired by Zachary Johnson. Non-continguous cartogram design invented by Judy Olsen. U.S. state and county boundaries from the U.S. Census Bureau, simplified using GDAL and MapShaper.
