Region

regionNode

Boundary polygons from a built-in pack, the basemap stroke. region(in: world) draws every country in Natural Earth's 1:110m admin-0 layer, and the admin-1 packs (us-states, canada-provinces, australia-states) draw a country's own subdivisions; only: and except: narrow it by name or ISO alpha-3 code. Unset, land fills with the neutral tint and borders read as seams of the page's own ground; a fill: hue fills with that hue's tint, a stroke: hue strokes in the hue itself.
