I'm interested in making an interactive 3D pie chart using JavaScript and ASP.net controls for a webpage. Essentially, I want to make an interactive version of the chart here: https://google-developers.appspot.com/chart/interactive/docs/gallery/piechart#3D
I want to have 5 ASP.net textboxes where the user enters data and then submits it, and the chart adjusts according to what the user enters. I understand using ASP.net controls with JS is probably not the most effective way to go about it, but I would really appreciate if someone could share how doing this would be possible. I really don't know where to begin.
Thanks for any help!
