Relation lines cross, but can be re-ordered to remove the crossing and simplify the diagram.
At the time of writing, loading the example diagram and arranging it horizontally gives this result.
Note the relation lines crossing in multiple places.
This can be reorganised so they don't cross. For example:
There are certainly going to be some diagrams where a re-arrangement like this isn't possible, but where it is, it would be helpful if the tool tried harder to find them.
