Looking through a key hole at a magnificent vista

The April 2009 issue of Popular Science contains a very fine information visualization of internet traffic flows (as part of its Who Protects The Internet? story). The diagram is the work of the research and consulting firm TeleGeography. They have a printed version of the diagram for sale but, sadly, its price is too steep for me. Popular Science's Flash-based online version of the diagram is a vivid example of being restricted to looking through a key hole at a magnificent vista. The diagram was meant to be printed large so you can take in its meaning. The diagram needed to be re-visualized for the web.

Does anyone know if the visualization was done at TeleGeography or somewhere else?
