Could you make an example or mock-up of such a layout?

It is indeed useful, but might also be confusing. The ad-hoc connections are
indeed ad-hoc, so they only appear if there is some traffic between two nodes.
Also, tinc only keeps track of its own ad-hoc connections, not of those in the
whole VPN. In tinc 1.1, there is actually some information about the
ad-hoc connections in the graph output: the color of the nodes indicates
whether that node is reachable directly or indirectly, or whether a direct
connection has not been attempted at all.

Tinc also doesn't keep track of whether LocalDiscovery had any influence on a
direct connection or not, at the moment the only way to figure that out is to
check the address used for UDP traffic.
