any good class for generating graphs and pie charts

Question

hi!

I'm working on a project which includes generating pie and bar graph charts on the fly with user inputs.

Can anyone suggest me some good libraries to do that?

It can be any like jquery, css, php class or anything free..

And i'm going to use it mainly offline. Thanks :)
