I am looking for a plugin that would do what google chart does. Unfortunately I haven't found it yet.

jQuery's flot sounds pretty good and is the closest to what I am looking for.
I think dojo is pretty good at charts, but after browsing their dojox, but I'm not sure how the library works, and if you have to write plugins yourself, or if existing ones are available.

Any advice on a good charting system, which allows zooming and data interaction?
