Concept Map

http://www.chartball.com/tweets/

This shows a concept map with an adjustable scale. It is also a proportional circle map. This shows the sports world based on number of followers each entity has on Twitter. The more followers someone has, the bigger his dot is. The concept map part of it shows the relationships between the different sports casters and players based on who is interested in them, and the adjustable scale means that you can choose one area (or one person) and delve into the nuance of the map. This type of map is useful to fantasy football players everywhere, but more practically to show the bigger sports stars and show the public interest in them visually.
