The new release of the google chart wrapper is uploaded and ready for download.
We improved a lot of things (javadoc, charts, unitTests ...), but some features are still not fully implemented in this release. It would be nice if you give us feedback about the way how you look at the API working (method names, structure ...). Further, we are interested if you like the usability and what could be improved.
