networkx.drawing.nx_agraph.from_agraph

from_agraph(A, create_using=None)[source]

Returns a NetworkX Graph or DiGraph from a PyGraphviz graph.

Parameters

  • A (PyGraphviz AGraph) – A graph created with PyGraphviz

  • create_using (NetworkX graph constructor, optional (default=None)) – Graph type to create. If graph instance, then cleared before populated. If None, then the appropriate Graph type is inferred from A.

Examples

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

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.
