Title: Difficult graph for dot
Submitter: Anthony Lansbergen

This graph causes dot a variety of problems when the cross column
edges are added. If the column nodes are not points, edges cannot be formed.
When edge labels are used, the columns start to interlace.
Even without edge labels, it is impossible to keep the columns straight,
even with heavy weights.
