[TriLUG] Web App with Bar Graph - What to Use?

[Glenn Hennessee]

Take a look at JFreeChart, a java based graphing library from 
sourceforge.net. The url is http://www.jfree.org/jfreechart/
I haven't used it but I ran across it recently and it may do what you're 
looking to do. They also give links to other free graphing/chart 
libraries at http://www.jfree.org/jfreechart/faq.html#FAQ13
