You need to remember that those types of splines need extra points which don't
visibly show up in the sphere sweep.

hit F1 and look up the cubic_spline tutorial in the documentation.

Just add an extra point to the beginning and end (copy the start and finish
points, maybe shift them slightly) and that ought to get you started.

I often use VISO to design such shapes, but you can probably use any graphics
program that will give you the pixel location of the mouse pointer, and there is
also
