JSON

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/

node_link_data(G[, attrs])	Returns data in node-link format that is suitable for JSON serialization and use in Javascript documents.
node_link_graph(data[, directed, …])	Returns graph from node-link data format.
adjacency_data(G[, attrs])	Returns data in adjacency format that is suitable for JSON serialization and use in Javascript documents.
adjacency_graph(data[, directed, …])	Returns graph from adjacency data format.
cytoscape_data(G[, attrs])	Returns data in Cytoscape JSON format (cyjs).
cytoscape_graph(data[, attrs])
tree_data(G, root[, attrs])	Returns data in tree format that is suitable for JSON serialization and use in Javascript documents.
tree_graph(data[, attrs])	Returns graph from tree data format.
jit_data(G[, indent, default])	Returns data in JIT JSON format.
jit_graph(data[, create_using])	Read a graph from JIT JSON.
