Tile choropleth maps like those created with the statebins R package usefully preserve the general placement of states (and terroritories) while removing differences in size that can skew interpretation of data unrelated to land area. This repository creates lightweight GeoJSON and TopoJSON tile files that can be used in any GIS program or package that accepts such files (_e.g., R, Python). In addition, they include squares for the five permanently inhabited US territories: American Samoa, Guam, Northern Mariana Islands, Puerto Rico, and the U.S. Virgin Islands.
Pre-built spatial files are located in the geo directory.

To build the geojson and topojson files, make ./scripts the working
directory, and run make_geo_data.R.
To create the example figures, next run make_example_figures.R.
The arrangement of the map tiles is modified from code provided in the statebins R package.
