globalization is already there…

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.

Decimal time zones and IATA codes, in the order of longitude:

  • 0          LON      London, UK
  • 0          PAR      Paris, France
  • 0          LOS      Lagos, Nigeria
  • 1          IST       Istanbul, Turkey
  • 1          CAI       Cairo, Egypt
  • 1          MOW    Moscow, Russia
  • 1          THR      Tehran, Iran
  • 2          KHI       Karachi, Pakistan
  • 2          BOM     Mumbai, India
  • 2          DEL       Delhi, India
  • 2          CCU      Kolkata, India
  • 3          DAC      Dhaka, Bangladesh
  • 3          JKT       Jakarta, Indonesia
  • 3          CAN      Guangzhou, China
  • 3          BJS       Beijing, China
  • 3          MNL      Manila, Philippines
  • 3          SHA      Shanghai, China
