US History Maps

This project collects the map assets (Shapefiles and GeoJSON) that were used for the "Manifest Destiny" Visualization

For each map on the right you can download both the Shapefile and the GeoJSON file. The simplified versions group shapes by category (US State, US Territory etc), yielding fewer shapes and smaller filesizes.
