Advice on ordering in erDiagrams: What's the general rules?

[EliW]

So yes, I know a lot of the point of Mermaid is that you don't worry about layout. And I love that. But I also know that you can often influence the way Mermaid decides to lay out a design based upon:

1. The order in which you define each element
2. The order in which you define the relationships
3. The cardinality of the relationships

But while I know that, I sometimes look at a chart and thing "ooh, if I could just move 'that section over there'. And I'll think I know exactly what to do to accomplish that. But I try, and nothing changes.

Just curious if anyone has a good summation of in general how Mermaid applies said logic, to know, for example, if I really want to move a specific element to the left of another, versus to the right, what changes I'd need to make, etc.
