Note:
(a) In print:
(i) There is NO this paragraph: "Fueled by billions of dollars in expansions, airports in the wealthiest Arab nations are becoming the world's busiest."
(ii) There is the credit at lower left corner of the graphic: FLIGHT PATHS BY JOHN O'SULLIVAN; PATHS SHOW DOMESTIC AND INTERNATIONAL FLIGHTS. AIRPORT DATA AND RANKING BY ACI WORLD

(b) The graphic views the earth from North Pole, which makes sense. Southern hemisphere (think Australia) is unlikely to host hubs.
(c) Taipei (ranked 16 for "number of international passengers") is one notch above New York (17). No PRC cities (except Hong Kong, that is) appears in the ranking. Beijing as well as Shanghai may draw world-ranking tourists each year, but obviously are not enough. I used to envy Japan as a transportation hub (almost every time I travel between Taiwan and Midwest and Eastern seaboard of United States, my planes stopped over in Tokyo Narita airport (No 13)--once in Incheon airport (No 9). It turns out that the geographic location of Taiwan is not bad. These international passengers, of course, just lay over, usually do not go out of airports to spend locally.
