Quoting Ben <[email protected]>:
That is great. Now, is there someway to permanently associate those two
parameters to the graph? i.e., G.show() has the colors and title?
AFAIK no.
You can set positions for vertices with set_pos() and you can attach
an arbitrary value to a vertex like
G.set_vertex(2, 'red')
but there seems to be no way to otherwise set default options. There is
G.graphics_array_defaults
that says among other things "'graph_border': True", but it seems to
have no effect. Hopefully someone can tell what for it is.

New version of Sage will make it possible to say
G.show(vertex_color='red', vertex_colors={'blue': [0, 1], 'green': [2, 3, 4]})
so that you can have a default color for vertices not listed in
vertex_colors. Same will be available for edge colors.
