Technically there are no connections between the relays in the protocol. Notes can be moved between relays but there is no P2P layer (yet) that moves these notes. Each User connects to their own set of relays (maybe better use a user icon in combination with the app icon). One user/app should connect to multiple relays.
So this is way better https://i.nostr.build/A6LqnPVyYdnKG1YO.jpg
