Re: self-loops in graphs

[Jeff Kingston]

>From memory you can draw a self-loop like this:

    XX:: @Circle { ... }
    //
    @CurveArrow from { address@hidden } to { address@hidden }

I haven't done this for a while, but I seem to remember that you have
to give points on the boundary of the node, use a curved path, and
also (which I haven't shown) fiddle with the bias parameter.
