Question: How to plot in spherical coordinates?

Hi!

This might sound like a simple question, but I have looked pretty hard in the documentation and can't find a solution.  I want to plot functions in spherical coordinates in such a way that they are actually spherical.  For example, r = 1 should be a sphere.  All I can do is get the "cube" with sides labelled as the traditional variables r, theta, and phi.  That's not really spherical coordinates, it's just relabelled Cartesian.

I didn't make a worksheet for this topic.

Thanks in advance for your help!
