Return a new graph, the composition of supplied graphs
Composition is the simple union of the node sets and edge sets. The node sets of the supplied graphs need not be disjoint.
Parameters : | graphs : list of graphs
name : string
|
---|---|
Returns : | R : A new graph with the same type as the first graph |
Notes
A new graph is returned, of the same class as the first graph in the list. It is recommended that the supplied graphs be either all directed or all undirected. If a graph attribute is present in multiple graphs, then the first graph in the graphs_list with that attribute takes priority for that attribute
