Here is a goldmine of sports visualization stuff that I found by doing some google searches. One thing this has revealed to me is that while I plan on concentrating on baseball because its what interests me the most and has the greatest possibilities as far as numerical data (that may not be true but I’m thinking it is…), its foolish for me to look for inspiration/precedence just within the realm of baseball. There are several awesome visualizations listed here which are for many other sports. One of the most intriguing that I see is the basketball vis showing where all shots from last seasons where taken from on the court. I plan on going through this page a lot more thoroughly in the near future.
