[BioC] help with rendering layers in Rgraphviz

I am using Rgraphviz in "neato" mode to layout a graph with about 500
nodes and 1500 edges. Rgraphviz first renders the nodes and then the
edges, meaning that I have a lot of edges overlapping with nodes. I
would like to put the edges behind the nodes to avoid this.
In reviewing documentation of both Graphviz and Rgraphviz, I do not
think using the "no overlap" option would work with a graph of this
size. Being able to see each and every edge is also not important for my
application, so I am wondering if I can use layers to render the edges
in a layer behind the nodes.
Will this work? If not, any other suggestions? If it will, could an
expert supply me with some sample code to render edges and nodes in
separate layers? I could not find any in the documentation I reviewed.
