3 · Use it
The cleaned CSV appends gid (mapjson's join key), the canonical
name, and ISO/FIPS codes to your data. Boundary features from
api.mapjson.com/v1/geo carry the same
gid, so drawing a map is a dictionary lookup: feature gid → your value → a color.
The build page does exactly that — drop this CSV on it and
watch it become a choropleth, code included.
