Read GraphML file to a MetaGraph.
Step1: Read the xml file.
Step2: Create a MetaGraph/MetDiGrap and add vertice in ascending order with Int vertice ID. Save the original id of the vertice to node attribute :original_id.
Step3: Save vertice attribtes and edge attributes to MetaGraph/MetaGraph.
Load GraphML file to a MetaGraph object
file_path = joinpath( "data/large_traffic_network.graphml" )
G = loadgraphml( file_path ) # return a MetaGraph object
Get the attributes of the nodes
node_fields(G)
Get the attribute of the edges
edge_fields(G)
Get the dict of the old id
ids = gmlid2metaid(G) #{od_id=>new_id, ...}
Test data: "data/large_traffic_network.graphml"
Graph size,
node number: 109,743
edge number: 379,474
