dynetx.readwrite.json_graph.node_link_data(G, attrs={'id': 'id', 'source': 'source', 'target': 'target'})

Return data in node-link format that is suitable for JSON serialization and use in Javascript documents.

Parameters:

• G (DyNetx graph) –
• attrs (dict) – A dictionary that contains three keys ‘id’, ‘source’ and ‘target’. The corresponding values provide the attribute names for storing DyNetx-internal graph data. The values should be unique. Default value dict(id='id', source='source', target='target').

Returns:

data – A dictionary with node-link formatted data.

Return type:

dict

Examples

>>> from dynetx.readwrite import json_graph
>>> import dynetx as dn
>>> G = dn.DynGraph([(1,2)])
>>> data = json_graph.node_link_data(G)

To serialize with json

>>> import json
>>> s = json.dumps(data)

Notes

Graph, node, and link attributes are stored in this format. Note that attribute keys will be converted to strings in order to comply with JSON.
