JFreeChart is a free (LGPL) chart library that supports a large number of chart types from pies, bars, lines and scatter plots. The JFreeChart API is quite flexible. I was able to easily wrap my code around a JFreeChart to make the charts interactive. Here's an example of a visualization of the music space that shows a musical journey from one style of music to another. All using JfreeChart:


We use JFreeChart to visualize usage data from Grid Engine for utility computing. We found it powerful enough for our needs without being too cumbersome. It does have its limits, though.
