Hi Eric,
Thank you for your interest. At this point we have no immediate plans for adding 3D support or funnel chart type to the RadChart control but still we will forward your feedback to our developers for further consideration.
As for the looks of the control -- we are constantly trying to polish the appearance of the produced image and as a step forward for Q1 2008 we added background images out-of-the-box for some of our skins (namely Mac, Inox, Metal, Marble, and Wood skins).
Kind regards,
Manuel
the Telerik team
