Global, Hub, Local level Architecture in Visio

Hello our company is very very large and complex and I am hoping you all could help me or help me find an appropriate article for laying out the modern SharePoint Information architecture using Visio.

1. Do we finally have co-authoring on Visio yet?
2. Do we have templates for Global, Hub, Local level information architecture, associated with modern SharePoint sites?
3. If we do have that template, is it dynamic to represent the current state of the organization?

I am very excited that Visio has a road map, and look forward to its future.
