globalization is already there…

Update is there are 260 direct flights between 26 megacities already, average is 10 flights. Graph is designed as in the initial note. Megacities are labeled by their IATA codes. 

This time, size of circle is due to betweeness centrality of megacity. The center of the graph is brighter than periphery. Color is due to calculated modularity classes:

• Green: LON, LOS, IST, CAI, MOW, THR, KHI, BOM, DEL, CCU.
• Red: DAC, JKT, CAN, BJS, MNL, SHA, SEL, OSA, TYO, LAX.
• Yellow: MEX, NYC, SAO, RIO, PAR. 

Calculated modularity classes are not exactly due to distribution neither by continents nor by oceans nor by decimal time zones. Globalization is already there at level of connections between megacities.
