There is no way to control the aspect ratio of plots made with
gnuplot, so you probably won't have much luck getting a circle.
I also don't know if you can make it draw a polar grid for you (unless
you want to specify all of the grid lines yourself).

I am currently working on integrating plplot with Octave, so I think
all of this will change for the better with 1.2.

(No, I still don't know when that will be ready :-).
