The globe layout puts every dot on a sphere instead of in the plane. Rows are latitudes, so they converge towards the pole and bow as it leans in, and each dot fades smaller as the surface turns away. Spacing is measured on screen rather than in longitude, which is what keeps the rim from piling up. The silhouette is still made of the units, one per 10 million people.
1 dot = 10 million people
