Hidden edges in Graphviz

I'm trying to create a graph using Graphviz开发者_StackOverflow (complied with neato), and I would like to place nodes in specific locations. For this, I'm specifying exact edge lengths for all edges. However, I don't want all edges to be visible in the final image.

Do you know of any way to hide edges? I should mention that I tried coloring the edges white, but what happens is that I get white lines painted over the graph nodes - it's not very aesthetic...

It can be done using

nodeA -> nodeB [style=invis]

I found out that another way to go is to define:

outputorder="edgesfirst"  

for the graph.
