I know the following libraries for drawing charts in an SWT/Eclipse RCP application:

* [Eclipse BIRT Chart Engine](http://www.eclipse.org/articles/article.php?file=Article-BIRTChartEngine/index.html) (Links to an article on how to use it)
* [JFreeChart](http://www.jfree.org/jfreechart/)

Which other libraries are there for drawing pretty charts with SWT? Or charts in Java generally? After all, you can always display an image...
