In this video we use GeoGebra 3D from geogebra.org to graph an ellipsoid with equation x^2 + y^2 + 9z^2 = 9 in rectangular and rho = 3/sqrt(1+8cos(phi)^2) in spherical  (See where equation comes from: Converting to Spherical Coordinates: ...).  We create a function for rho and then use the surface command with parameters for theta and phi (I use t and v).  After getting the graph to work we then create sliders for the upper bounds of the parameters and play around with it a bit.  Playing around with this kind of thing on GeoGebra is the best way I've found to really learn what's going on.
