Is it possible to create intersecting/overlapping containers at Deployment Diagram?

Question

I would like to show different security groups of a cloud deployment as round corner rectangles.
If a node in the cloud is included into two groups at the same time then the groups containing it should overlap/intersect.

I've tried to use an alias within the second rectangle (group) containing the same element and got syntax error:

@startuml

rectangle A {
  rectangle X as X1
  rectangle Y
}
rectangle B {
  X1
}
@enduml

Also I've tried to name with the same name the inner element included into both groups like this:

@startuml
rectangle A {
  rectangle X
  rectangle Y
}
rectangle B {
  rectangle X
}
@enduml

It results in two separate rectangles with different X elements inside each rectangle.

Answer 1

Sorry, but it's really not possible to have groups that overlap/intersect .

So you cannot draw something like that :

(I think it's what you are looking for)

That would be hard to compute, and would quickly become impossible.

BTW, the best library for Venn diagrams that can handle more than 3-4 intersecting sets is venn.js

@valexiev,
what's the math behind that tell us it would be hard to compute such diagrams?
