This is a really cool module. It's something we've wanted to create since the very first version of Form Tools, some 6 years ago at the time of writing. However - it's not perfect! Not by a long shot! The wonderful thing about data is that it can visualized in any number of ways - here's no end to the way you can clarify and summarize information to improve understanding.
So! What do you want to see? What sort of charts would you like to see added? What kind of problems do you encounter that a good visualization could help solve?
Please let us know through the forums. We're very much looking forward to your suggestions - we take them very seriously.
