easygraph.readwrite.json_graph.node_link module

easygraph.readwrite.json_graph.node_link.node_link_graph(data, directed=False, multigraph=True, attrs=None)

Returns 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 EasyGraph graph object

Return type:

EasyGraph graph

Examples

>>> from easygraph.readwrite import json_graph
>>> G = eg.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.

Module contents

JSON data

Generate and parse JSON serializable data for NetworkX graphs.

These formats are suitable for use with the d3.js examples https://d3js.org/

The three formats that you can generate with NetworkX are:

• node-link like in the d3.js example https://bl.ocks.org/mbostock/4062045

• tree like in the d3.js example https://bl.ocks.org/mbostock/4063550

• adjacency like in the d3.js example https://bost.ocks.org/mike/miserables/
