read_dot(path)[source]

Returns a NetworkX MultiGraph or MultiDiGraph from the dot file with the passed path.

If this file contains multiple graphs, only the first such graph is returned. All graphs _except_ the first are silently ignored.

Parameters

path (str or file) – Filename or file handle.

Returns

G – A MultiGraph or MultiDiGraph.

Return type

Notes

Use G = nx.Graph(read_dot(path)) to return a Graph instead of a MultiGraph.
