Re: [graphviz-interest] Moving nodes and edges between [sub]graphs using the gv library

So, to move a node from one subgraph to another I would need to create
a new node, copy all the attributes, create copies of all the existing
edges to/from the old node, copy all of their attributes, then delete
the old node (and the old edges?)?
