I think that might be possible, I may have turned off the labels on the
edges.

The layouts were all built in the DataGrip luckily!

I think SchemaSpy's new output looks really interesting and uses
Graphviz. After doing the work to add the relationships I realised that
SchemaSpy does not like the oid system columns that we use for keys so
it wouldn't work. I will go ahead and replace them all with something
else and see how it does but I haven't gotten back to it yet.
