[Trisquel-users] JFreeChart, free software? Free Alternative?

[dooleyn]

Hi,

I'm looking to maybe use a tool such a JFreeChart. However, I'm not sure if  
it is considered free software. It is not listed in FSF directory and  
wikipedia states it is an 'open source framework'. The projects website  
though states it is free software (http://www.jfree.org/jfreechart/). Have  
others had any experience with using this software? If it is not free  
software can you suggest a free software alternative? I'd be very grateful.

Thanks in advance.
