networkx.readwrite.json_graph.node_link_graph

node_link_graph(data, directed=False, multigraph=True, attrs=None)

Return graph from node-link data format.

Parameters:

• data (dict) – node-link formatted graph data

• directed (bool) – If True, and direction not specified in data, return a directed graph.

• multigraph (bool) – If True, and multigraph not specified in data, return a multigraph.

• attrs (dict) – A dictionary that contains five keys ‘source’, ‘target’, ‘name’, ‘key’ and ‘link’. The corresponding values provide the attribute names for storing NetworkX-internal graph data. Default value:

  dict(source=’source’, target=’target’, name=’id’,

  key=’key’, link=’links’)

Returns:

G – A NetworkX graph object

Return type:

NetworkX graph

Examples

>>> from networkx.readwrite import json_graph
>>> G = nx.Graph([('A', 'B')])
>>> data = json_graph.node_link_data(G)
>>> H = json_graph.node_link_graph(data)

Notes

Attribute ‘key’ is only used for multigraphs.
