### Description

Create this graph:

sage: F = GF(3) sage: gens = [matrix(F,2,[1,0, 1,1]), matrix(F,2, [1,1, 0,1])] sage: group = MatrixGroup(gens) sage: G = group.cayley_graph()

It is not too big:

sage: G Digraph on 24 vertices

Note that since the vertices of G are matrices, the default `format='tkz_graph'`

does not work. One need to use `format='dot2tex'`

. With dot2tex-2.8.7-2 and graphviz installed, this works:

sage: G.set_latex_options(format='dot2tex', prog='neato') sage: view(G)

But not this one:

sage: G.set_latex_options(format='dot2tex', prog='dot') sage: view(G) An error occurred. ... LaTex error

I know a workaround which is to use the tikz2pdf script which compiles fine. But, it would be nice if view could compile G as well.
