Miller cylindrical projection, generalized overview and preprojected country detail
produced with d3-geo 3.1.2, topojson-client 3.1.0 and topojson-simplify 3.0.3.
These are data preparation tools, not runtime dependencies.
Country membership/area threshold metadata: world-countries 5.1.0 (ODbL),
https://github.com/mledoze/countries. The original canonical country list and
license remain available at /data/countries.json and /data/countries-license.txt.
Generated atlas metadata derived from that database is likewise available under
ODbL in public/atlas/index.json. Country classification is unchanged.
Geography reflects source boundary conventions, including disputed areas; it is
not a legal boundary authority. Vatican City geometry is degenerate and retains
a locator. Tuvalu is absent at 50m and receives a locator until detailed geometry
has a usable projected footprint.
