Generalized Natural Earth geography; public domain. Coordinate projection is an equirectangular study view with standard-parallel scaling. Boundaries are not a political-status claim. Physical region, mountain, marine and archipelago polygons are approximate label-area extents. Rivers use real mapped drainage lines; lakes use mapped shorelines.
Dots help you find small places. They mark a location, not the full outline or size of a place.
