title: Hidden edges in Graphviz
body: <p>I'm trying to create a graph using Graphviz (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. <br>
  <br>
  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...</p>
