Parameters ---------- G : NetworkX graph G must be an oriented tree root : node The root of the tree ident : string Attribute name for storing NetworkX-internal graph data. `ident` must have a different value than `children`. The default is 'id'. children : string Attribute name for storing NetworkX-internal graph data. `children` must have a different value than `ident`. The default is 'children'. Returns ------- data : dict A dictionary with node-link formatted data. Raises ------ NetworkXError If `children` and `ident` attributes are identical. Examples -------- >>> from networkx.readwrite import json_graph >>> G = nx.DiGraph([(1, 2)]) >>> data = json_graph.tree_data(G, root=1) To serialize with json >>> import json >>> s = json.dumps(data) Notes ----- Node attributes are stored in this format but keys for attributes must be strings if you want to serialize with JSON. Graph and edge attributes are not stored.
