GEXF (Graph Exchange XML Format) is a language for describing complex network structures, their associated data and dynamics. This implementation does not support mixed graphs (directed and undirected edges together). Format ------ GEXF is an XML format. See https://gephi.org/gexf/format/schema.html for the specification and https://gephi.org/gexf/format/basic.html for examples. iN(t open_filetmake_str(tElementt ElementTreet SubElementttostringt write_gexft read_gexftrelabel_gexf_grapht generate_gexfitmodetwbsutf-8s1.2draftcCs9td|d|d|}|j||j|dS(sWrite G in GEXF format to path. "GEXF (Graph Exchange XML Format) is a language for describing complex networks structures, their associated data and dynamics" [1]_. Node attributes are checked according to the version of the GEXF schemas used for parameters which are not user defined, e.g. visualization 'viz' [2]_. See example for usage. Parameters ---------- G : graph A NetworkX graph path : file or string File or file name to write. File names ending in .gz or .bz2 will be compressed. encoding : string (optional, default: 'utf-8') Encoding for text data. prettyprint : bool (optional, default: True) If True use line breaks and indenting in output XML. Examples -------- >>> G = nx.path_graph(4) >>> nx.write_gexf(G, "test.gexf") # visualization data >>> G.nodes[0]['viz'] = {'size': 54} >>> G.nodes[0]['viz']['position'] = {'x' : 0, 'y' : 1} >>> G.nodes[0]['viz']['color'] = {'r' : 0, 'g' : 0, 'b' : 256} Notes ----- This implementation does not support mixed graphs (directed and undirected edges together). The node id attribute is set to be the string of the node label. If you want to specify an id use set it as node data, e.g. node['a']['id']=1 to set the id of node 'a' to 1. References ---------- ..

Parameters ---------- path : file or string File or file name to write. File names ending in .gz or .bz2 will be compressed. node_type: Python type (default: None) Convert node ids to this type if not None. relabel : bool (default: False) If True relabel the nodes to use the GEXF node "label" attribute instead of the node "id" attribute as the NetworkX node label. version : string (default: 1.2draft) Version of GEFX File Format (see https://gephi.org/gexf/format/schema.html). Supported values: "1.1draft", "1.2draft" Returns ------- graph: NetworkX graph If no parallel edges are found a Graph or DiGraph is returned. Otherwise a MultiGraph or MultiDiGraph is returned.
