node_link_graph#

node_link_graph(data, directed=False, multigraph=True, attrs=None)[source]#

Returns graph from node-link data format.

Parameters:

datadict

node-link formatted graph data

directedbool

If True, and direction not specified in data, return a directed graph.

multigraphbool

If True, and multigraph not specified in data, return a multigraph.

attrsdict

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:

GNetworkX graph: A NetworkX graph object

Attribute ‘key’ is only used for multigraphs.

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)
