tree_graph

tree_graph(data, attrs={'children': 'children', 'id': 'id'})[source]

Return graph from tree data format.

Parameters:data (dict) – Tree formatted graph data
Returns:
  • G (NetworkX DiGraph)
  • attrs (dict) – A dictionary that contains two keys ‘id’ and ‘children’. The corresponding values provide the attribute names for storing NetworkX-internal graph data. The values should be unique. Default value: dict(id='id', children='children').

Examples

>>> from networkx.readwrite import json_graph
>>> G = nx.DiGraph([(1,2)])
>>> data = json_graph.tree_data(G,root=1)
>>> H = json_graph.tree_graph(data)

Notes

The default value of attrs will be changed in a future release of NetworkX.
