Back in June we shipped support for viewing geographic data
to GitHub.com repositories in GeoJSON & TopoJSON formats, which was awesome for open data sets and collaborative projects.
We didn’t want to finish there, though. We wanted to make it easier to share data with others.
Now it’s easier! To share a map, just drag a GeoJSON or TopoJSON file over to a new gist and hit create.
🎉">
Gist will build your map for you and anyone you share it with for easy collaboration.
You can also use a service like geojson.io to compose a map and quickly save it
as a GeoJSON Gist.
Of course this still works if you embed the Gist anywhere else
on the modern internet.
