Tools to draw interactive Pie Chart in Swing application

Hello....

I am developing a swing application,,, in which there is a summary screen... i have used only swing components and awt components to develop the application...

Now i want to represent the data in the form of Pie Chart, and clicking on each part of the pie chart it should take me to another pie chart.How to do this, is there any free softwares which can be used to show the summary details in Pie Chart. If So Which are the best and user friendly tools. I checkd the sourceforge.net and found jfreechart, but it does not have a user manual for free..... Please guide...

Thanx.....
