Anjo Krank:

Simple wrapper around the JFreechart framework, which can be found here: http://www.jfree.org/jfreechart/

JFreechart is a very comprehensive open-source LGPL charting framework. ERPlot is a light wrapper around some of it's features so they can be used inside WOBuilder and webobjects in general.
