You are looking at the Oneworld Explorer RTW ticket planning and booking tool (http://rtw.oneworld.com/).

You want the oneworld Interactive Network Map tool (http://onw.innosked.com/?show=MAP).

They are both under the "Flights" drop down menu on the oneworld website. The booking tool under "Plan and Book" (3rd option), the map under "Where we fly" (1st option).
