3D data chart (x,y,z)

Do you have some Chart control which can accept 3-dimensional data (x,y,z) not only displays data in 2D dimensions (X and Y axis)?  If it does, could you please give me some sample code in C#.

Thanks ahead!

Currently for ASP.NET Ajax it would seem as if the RadChart does not support a third (Z-plane) axis. I looked over the RadChart for Silverlight which does have the ability to display Charts in 3D, but I didn't see a way to define points in the z-plane either.
