from_agraph¶

from_agraph(A, create_using=None)[source]¶

Return a NetworkX Graph or DiGraph from a PyGraphviz graph.

Parameters:

A : PyGraphviz AGraph

A graph created with PyGraphviz

create_using : NetworkX graph class instance

The output is created using the given graph class instance

Notes

The Graph G will have a dictionary G.graph_attr containing the default graphviz attributes for graphs, nodes and edges.

Default node attributes will be in the dictionary G.node_attr which is keyed by node.

Edge attributes will be returned as edge data in G. With edge_attr=False the edge data will be the Graphviz edge weight attribute or the value 1 if no edge weight attribute is found.

Examples

>>> K5=nx.complete_graph(5)
>>> A=nx.to_agraph(K5)
>>> G=nx.from_agraph(A)
>>> G=nx.from_agraph(A)
