I think the “How Whonix Works” picture should combine four things into a complicated illustration like Subgraph’s.
Effectively, you want to show:
- Separate host OS (Xen or other)
- Whonix-WS connecting to a Whonix-GW
- Whonix-GW choosing random paths through the Tor network with the last step (often) being an unencrypted link - this could be updated to show encrypted connections if .onions
- Stream isolation
If the illustrator is good enough, they need to combine the following three images below into something sensible. It probably could be a 3d image like Subgraph’s to fit it all in.
