Profile verification

One numeric measure per region, joined by feature ID or name. Keys are unique; unmatched features/records are explicitly reported. Fill encodes value, not region area.
Load the optional geo module and host-supplied GeoJSON; DDN does not fetch arbitrary geography URLs. Supported geometry is Polygon/MultiPolygon/Point/MultiPoint, wrapped as Feature/FeatureCollection or bare geometry.
Select mercator/equirectangular/albers/equalEarth; fit the declared projection, split antimeridian crossings, clamp Mercator latitude as implemented. Missing module produces a visible error placeholder, not a successful map.

Profile defaults

Explicit file settings override eligible CSS, then these profile defaults and the common standard apply. Unspecified semantic facts remain unspecified.

Design operations

Choose registered geography and projection; select records and bind region/value or coordinate/size channels; inspect unmatched joins and provenance.

Bounded analysis

Declared geographic projection, bounded joins and value encoding; no geocoding, spatial prediction or remote geography fetching.
