Example

=======

	// create new graph

	$gexf = new Gexf();

	$gexf->setTitle("Hashtag - user " . $filename);

	$gexf->setEdgeType(GEXF_EDGE_UNDIRECTED);

	$gexf->setCreator("tools.digitalmethods.net");

	

	// fill bi-partite graph

	foreach ($userHashtags as $user => $hashtags) {

		foreach ($hashtags as $hashtag => $frequency) {

		

			// make node 1

			$node1 = new GexfNode($user);

			$node1->addNodeAttribute("type", 'user', $type = "string");

			$gexf->addNode($node1);

	

			// make node 2

			$node2 = new GexfNode($hashtag);

			$node2->addNodeAttribute("type", 'hashtag', $type = "string");

			$gexf->addNode($node2);

		

			// create edge	

			$edge_id = $gexf->addEdge($node1, $node2, $frequency);

		}

	}

	

	// render the file

	$gexf->render();

	// write out the file

	file_put_contents('file.gexf', $gexf->gexfFile);
