Yes, it is simple:
sage: g=graphs.PathGraph(6)
sage: g.get_pos()
{0: [0, 0], 1: [1, 0], 2: [2, 0], 3: [3, 0], 4: [4, 0], 5: [5, 0]}
See g.get_pos? for an example of how to layout a graph if the position
dictionary is not specified in the graph definition.
You can set the position dictionary with g.set_pos().
Thanks,
Jason
