How to read this map and sources
The scope is 193 UN member states plus the two non-member observer states, a total of 195. These are illustrative connections based on port and airport locations, not actual services, road itineraries, timetables or border-access conditions. Air connections geometrically join real airport locations; they do not assert the existence of specific nonstop flights. Andorra, Liechtenstein, Monaco, San Marino, Vatican City and Palestine are represented by surface links to nearby airports. Ships follow a maritime network, while general land routes use Natural Earth road and railway geometry. Counts, line widths and speeds do not represent real traffic volume or actual speed. This is a modern geographic illustration, not a reconstruction of historical networks.
