I agree that the symbol is not nice, but unfortunately what I expect from "vectorial graphics" :)
The odot symbol is currently drawn with a circle and this could be improved (Olivier).
I see that line width (by default is set to 2) and some improvement can be obtained in setting the width to 1
and changing the scale. see example below.
