World civilization is based on the cities and the relationship between them.
In terms of distances on the graph, language is more important than just geographic location.
So, for civilization, language is more important than just geographic location.
Divergence between the graph and the world map
NB: French is Romanic as Spanish and Portuguese. English is Germanic.
Total 26 megacities (agglomerations over 10 millions people). Vertices of the graph.
Connections are regular direct flights between megacities. Edges of the graph.
Visualizing of the graph is force-based: connections are equally elastic; system is calmed.

Black circle: vertex is peripheral; maximum 2 stops to every city. Eccentricity equals 3.
White circle: vertex is central; maximum 1 stop to every city. Eccentricity equals 2.
White circle, blue ring: central; such cities are full cross-connected. A maximal clique.
Size of circle is due to number of cities connected by direct flights.
