Survey vs Polls and Charting / graphing?

This morning I have just loaded up new GF Survey add-on, and Polls. It isn't immediately clear to me what the difference between them is, but no worries I guess I'll work it out eventually. But... they both require specific survey or poll specific questions to be inserted into a form before displaying the results. Is there any way that GF can graphically display results from existing form fields (i.e. not special Poll or Survey ones)?

I have built a lean event booking system around GF and want to display some basic charts showing applicant numbers, demographics (age / gender / event balance etc). I suspect I'll need to get my hands dirty with php and java/jquery!

Love the plugin already, just looking for even more icing in the cake!!

Thanks Chris. FYI Daniel Grundel and Mahmoud Kassassir at Web Presence Partners have made available on Github a great charting plug-in for GF. They have used Raphael to render charts. Worked for me straight out of the tin, and I won't need to edit too much code to satisfy my needs.
