There's no way to add a circle shape to the graph currently, but we do have a feature request open in the development database.
If you really need a circle, the best workaround is to use numbers or some other program to sample *a lot* of points. 36 (one every ten degrees) seems to get around the "bump" at the start/finish pretty well. I've attached an .xls file.
