I have a directed graph to display using GraphPlot:
a=RotateVertices[EmptyGraph[4],-(\[Pi]/4)];
a=SetGraphOptions[a,EdgeDirection->True];
a=AddEdges[a,{{1,2},{2,3},{2,4},{3,1},{4,1},{4,3}}];
I want to display it using GraphPlot...
GraphPlot[a, Method -> None, DirectedEdges -> True,
VertexRenderingFunction -> ({Black, Disk[#1, 0.02]} &)]
... but I want the edges and the arrows to be Black and not the default
brown.
How can one do this WITHOUT having to completely rewrite what the
default EdgeRenderingFunction->Automatic option does; that is, I still
want the arrows with their heads in the default position (it looks
something like 2/3 the way along each arrow).
