I frequently use Visio to create architecture diagrams for computer systems. These diagrams often have multiple levels to them and it would be helpful for Visio to represent these. For example, I'll often use a cloud shape to represent Azure or AWS and then I put shapes within it to represent services they're running. The problem is that this often leads to a busy drawing that's difficult to consume.

It would be helpful to be able to zoom in to the cloud shape and place the shapes for services within it, similar to how one can zoom in and out of a computer-based map.

In this way, a user looking at the drawing could zoom in and out of each component to see the detail underneath. I'm thinking Visio would need some indication that content is available at levels above and below the level the user is looking at.
