[graphviz-interest] fdp layout vs dot layout

So when rendering the attached dot graph (
https://dl.dropboxusercontent.com/u/7096948/simple.dot) to an image using
the dot command

dot -Tpng bipartite_map_rcp.dot -osimple.png

I get a semi nice layout for all my nodes, with the exception of many of
the edges coming out wrong since dot doesn't support subgraph to subgraph
or subgraph to node edges (and instead creates new nodes with the names of
the subgraphs it was supposed to connect as shown by the image simple.png (
http://i.imgur.com/vnMKhZk.jpg)

If you instead use fdp
fdp -Tpng bipartite_map_rcp.dot -osimple2.png (http://imgur.com/4JKgag5)


You get some pretty messy layout, although the edges come out fine as shown
by simple2.png.

The question would be if there's a way to get fdp to use dot's default
layout while getting the edges right. Thank you.
