A Geoprocessing Tool to make Cartograms. Cartograms are a transformation of a map where the original polygons expand or contract their area based on an attribute value they have. A typical example is a cartogram made using the population of the original areas. See the Readme file for a more complete explanation. The install executable in the zip file will install some sample data. The tool uses the methodology developed by Mark Newman and Michael Gastner at the University of Michigan. Both the Readme and the Help for the Geoprocessing Tool have information about how to use the tool and how the process works.
