I'm working on a graph theory problem where it is very helpful to draw
the vertices of the graph in a line and then the edges as arcs between
the vertices. I can't seem to figure out how to alter where an edge
goes in sage, specifically wanting it to not go in a straight line.
Is this easily accomplished? Here is some sample (notebook) code so
you can see what I mean:
****************************************
g = graphs.RandomGNP(10,.5)
t = Graph()
t = g.steiner_tree(g.vertices()[:5])
t.plot()
pos_dict = {}
for i in range(5):
pos_dict[i] = [i,0]
t.show(pos=pos_dict)
****************************************
Chances are, the random graph you got will look like a path on five
vertices when it prints the second time, but it's only because all of
the edges are overlapping.
Thanks!
