from_node_link_json_file(path, graph_attrs=None, node_attrs=None, edge_attrs=None)

Parse a node-link format JSON file to generate a graph

Parameters:

• str (path) – The path to the JSON file to load

• graph_attrs – An optional callable that will be passed a dictionary with string keys and string values and is expected to return a Python object to use for attrs attribute of the output graph. If not specified the dictionary with string keys and string values will be used as the value for attrs.

• node_attrs – An optional callable that will be passed a dictionary with string keys and string values representing the data payload for each node in the graph and is expected to return a Python object to use for the data payload of the node. If not specified the dictionary with string keys and string values will be used for the nodes’ data payload.

• edge_attrs – An optional callable that will be passed a dictionary with string keys and string values representing the data payload for each edge in the graph and is expected to return a Python object to use for the data payload of the node. If not specified the dictionary with string keys and string values will be used for the edge’ data payload.

Returns:

The graph represented by the node link JSON

Return type:

PyGraph | PyDiGraph
