It might be that it's actually the bounding box of the small graphs
that is wrong. If you do:
sage: g = Graph({0:[1,2,3], 1:[2], 2:[3]})
sage: view(g, tightpage=True)
then on my machine the vertices get cropped in half. Rob, what do you think?
If I add the following line to your function so that the small graphs
are drawn by dot2tex instead:
G[1].set_latex_options(format="dot2tex", prog="circo")
then I get a reasonable picture (attached).
Cheers,
Nicolas

Note: I had to replace v.vertex by v to look at your example.
