Hi sage-devel,
Graph latex method outputs tikz code apparently using tkz-berge library.
Does anyone was ever able to compile tkz-berge code where vertices are some
array, tabular or matrices?
In tikz, I use to draw a graph using simply "node" and "edge" instead of
tkz-berge library and I know it is possible to put some array inside a node
and make it compile... Is coding a new version of _latex_ method using
basic tikz code my only solution?

sage: m = matrix(3, range(9))
sage: m.set_immutable()
sage: G = Graph()
sage: G.add_vertex(m)
sage: latex(G)

Here is the error I get :

If you say, e.g., `\def\a1{...}', then you must always
put `1' after `\a', since control sequence names are
made up of letters only. The macro here has not been
followed by the required stuff, so I'm ignoring it.
