I'm guessing you want a weighted graph such as the following:
sage: version()
'Sage Version 4.6, Release Date: 2010-10-30'
sage: edge_dict = {
....: "New York": {"London": 5586, "Paris": 5851, "Berlin": 6402},
....: "London": {"Paris": 341, "Madrid": 1264},
....: "Sydney": {"Beijing": 8923, "Bangkok": 7524}
....: }
sage: G = Graph(edge_dict, weighted=True)
sage: G.vertices()
['Bangkok', 'Beijing', 'Berlin', 'London', 'Madrid', 'New York',
'Paris', 'Sydney']
sage: G.edges()
[('Bangkok', 'Sydney', 7524), ('Beijing', 'Sydney', 8923), ('Berlin',
'New York', 6402), ('London', 'Madrid', 1264), ('London', 'New York',
5586), ('London', 'Paris', 341), ('New York', 'Paris', 5851)]
But I can't figure out how to get G.show() to display the edge weights.
