I was wondering what was the best technique to merge multiple graphs.
The union methods appears to merge the nodes based on node id. If I
wanted to merge the graphs based on a label in the node, whats the best
approach? I was thinking of adding both graphs, iterating through all
the vertices and removing duplicate labels and adding new edge that
belong to the ones that got removed. Is this a sensible approach?
