make subgraph areas not overlap
I want to display a network consisting of data centers and carrier links in between. Unfortunately, instead of laying out the nodes within the cluster subgraphs and afterwards layouting the subgraphs and the inter-subgraph links, neato layouts the whole graph first and then afterwards draws the areas around the sugraphs.
This results in overlapping subgraphs.
How can I make the subgraphs not overlap.
Also, it would be nice if I could roughly position the subgraphs.
Any help or pointer is appreciated.
