http://ask.sagemath.org/question/8572/can-i-show-the-edge-weights-on-a-graph-in-a-drawing/?answer=13155#post-id-13155Two more points: First, I found the following site helpful for displaying graphs
http://www.sagenb.org/home/pub/2351/
Second, graphviz is really great at displaying graphs with edge labels and many other decorations. Its a whole graph layout programming language, but it can't be included in sage because of a licensing issue apparently. The link above shows how to output a graph from sage to a dot file suitable for graphviz. For example, after downloading graphviz on your computer, you can run "dotty file.dot".

http://ask.sagemath.org/question/8572/can-i-show-the-edge-weights-on-a-graph-in-a-drawing/?answer=13110#post-id-13110Don't know how to animate a graph, but
G = DiGraph(A, format='weighted_adjacency_matrix')
H = G.plot(edge_labels=True, graph_border=True)
H.show()
will display the weights in a graph with adj matrix A.Tue, 10 Jan 2012 14:54:14 -0600http://ask.sagemath.org/question/8572/can-i-show-the-edge-weights-on-a-graph-in-a-drawing/?answer=13110#post-id-13110
