I have just submitted a small module to the Code Exchange that allows the creation of Charts (via the Google chart API) in your apps. No idea if it will help anyone but I was bored.
It currently only supports Pie and QR but others are coming when I find the time.
just to clarify for people, this returns a static chart image based on the data you submit to the Google API. [import]uid: 6645 topic_id: 6887 reply_id: 24077[/import]
