# plot graphs with graph in vertices

I have a graph whose vertices are made of graphs. Is there a way to plot them nicely from Sage? Doing

```
sage: G0 = graphs.PetersenGraph().copy(immutable=True)
sage: G1 = graphs.CycleGraph(4).copy(immutable=True)
sage: G = Graph([(G0,G1)])
sage: G.plot()
```

The names of the graph are in the vertices not the graphics of them.

If there is an option in the graph plot to use an alternate name for them, perhaps you could hack the

`_repr_`

or whatever to do this ... hmm.Ticket 21918 could help...

Note: a similar question was asked on StackOverflow. So far no answer there.
