Any good books on graphing/charting/visualization?
anonjon: You might want to check out the processing language at:http://www.processing.org/And look at the examples section.A lot of it is about artistic sorts of representation, but it is programmatic. There are a few books that the authors of the language wrote, including the visualizing data book mentioned by duck. (They are mentioned on the front page of processing.org).It is a pretty neat language, and the core functionality can be used as a Java library. (I have been working through the 'processing a programming handbook', and it is more about using the language than about ways to display the data (So you might want to pick one of the other books)).
