That said, I've created the following GraphViz graphs to show some of the new functionality of the new backend. This page will be updated from time as I think of it if I get around to graphing any other cool features.
So without further ado, here's a couple of GraphViz graphs showing off a new feature of the backend, the ability to grab routing information through SNMP. Note that in these graphs, nodes are labeled only with their unique numeric identifiers. It's a trivial matter, however, to show either one or all IP addresses associated with a node, or label each connection with the destination network and netmask. For the privacy and security of the test network, these were removed.
Note: The last one's a PostScript file because browsers may have difficulty handling the PNG.
