Is there a way to render a self-loop in a Graph component in a custom way? Currently if I create a GraphConnection so that it is a self-loop I will only see a simple arrowhead on the side of the node. I would like to see a curvy line which is more visible. MAybe is it possible to specify some bendpoints?

It currently only works for graph viewers, not plain graphs - see bug 190223.

Thanks, this was actually useful because I can set the curve depth for the GraphConnection. I have however two more questions:
-How can I position the label text on the connection? If I set to curve depth other than 0, the label will appear close to the source or target node. When the depth is set to 0, it is positioned to the middle of the connection arc.
-How can I influence the layout algorithm? When I have two strongly connected components then one of them is placed on the upper left corner, the other on the lower right and each one of the subgraphs are really crowded even if there is a lot of space available.
