The Atlas of the Real World provides a potentially powerful visual tool that re-sizes nation-states on a globe based on their rank or gravity on particular issues:
The Atlas of the Real World uses software to depict the nations of the world, not by their physical size, but by their demographic importance on a range of subjects. Here, we select a series of travel- and news-related maps
Starting with basic land mass, the 18-globe series has some highlights such as Net Tourism, use of airplanes, and Post-WWII war deaths. Obviously it is not a new technique, but the quality and breadth of the collection is worth a link! Also, given that I spent a few hours looking at topographic maps this afternoon, this is a welcome change of perspective.
