Interesting to see FedEx get into the mapping and visualization business, though not surprising because they’re active participants in a global distribution network of information.
They chose to make cartograms, a cartographic format that will confuse the uninformed casual observer of these maps but may inspire some additional learning (about mapping and about the interaction of the variables). Cartograms distort the size and shape of a mapped area (in this case, countries) on the basis of some variable. If cartograms float your boat, check out these at Worldmapper.
