A question was asked recently on the SuperUser forum:
https://superuser.com/questions/1378502/can-i-add-a-webpage-browser-to-a-visio-diagram about how to add a view of a web page from a Visio diagram.
There is no built-in method of doing this but I thought I might be able to modify my Output Dialog for Visio, and I have managed to get something working.
Just install this addon, then run the file "test web page output.vsd" which the installer adds tou your desktop so it is easy to find.
The browser window may be moved and resized as required.
