PacketDesign RouteExplorer does good visualizations based upon BGP
and IGP, and Narus InSight Manager does visualization based upon
BGP. There are also tools like lanmap, which watch packets via RSPAN
in a given locality.
Several of the open source and commercial NMS systems do SNMP-based
autodiscovery; it's important to test these out and ensure they're
tuned not to be overly aggressive prior to running the autodiscovery,
monitor your network while it's taking place, do it during a
maintenance window, etc.
Some folks use GraphViz with a bit of Perl-fu on their configs to
generate graphs, too.
