Obtaining an unmodified latex output via Sage

edit

I use the following in Sage to obtain latex output of a digraph:

G=DiGraph([(2, 1), (4, 1), (4, 0), (3, 4)])
display(G)
latex(G)

The picture of the digraph (via display) looks nice in Sage, but the latex code gives me bend edges.

Question: Is there a way to make Sage give me latex output that looks like the display in Sage? Or at least is it possible to give me output with straight edges instead of bend edges and make the head of the arrows bigger?
