I've found lots of discovery tools, but intelligent mapping/layout still
seems to be a problem. The usual requirements for SNMP smart discovery,
interface/subnet mapping, device identification and connecting the right
symbols with the right lines to all the other symbols.

That's quite a "medium-scale".

Is there a single entity in the world that controls 1,000 networks and
100,000 network devices?

I am a network engineer for a cable ISP.  We have over 50,000 cable modems
and around 65,000 customer devices.  We only have 200-250 networks, but
well over 100,000 ip devices.
