This is an informal, cobbled together collection of geoJSON and topoJSON maps.
Where the source is known, we've provided it, either in a metadata JSON file, or in the geoJSON/topoJSON file itself in an off-spec 'datasource' field.
If you have additional maps, please make a pull request.
Special thanks to Marcin Wichary and the rest of the creators of Click that Hood for gathering a lot of maps and giving me permission to repost their work.
