# World Capitals Voronoi Source: [https://www.jasondavies.com/maps/voronoi/capitals/](https://www.jasondavies.com/maps/voronoi/capitals/) Data:[Natural Earth, 1:10m Cultural Vectors: Populated Places \(Admin\-0 capitals\)](http://www.naturalearthdata.com/downloads/10m-cultural-vectors/10m-populated-places/)\. World territories have been redrawn so that a region is determined by the closest capital city\. This is calculated using a[spherical Voronoi diagram](https://www.jasondavies.com/maps/voronoi/), which takes into account the curvature of the Earth when computing distances\.
