umbrella is an OpenGL based graphing tool, that reads
the graphviz graph file format.
It began life as gpgl, which was designed to display GPG webs
of trust.
umbrella is being used to display computer networks, and the goals
include tying the tool into other network tools such as nagios, mrtg, SNMP traps, and so on, to provide a pretty eyecandy map of ones network,
suitable for displaying on the biggest screen in the NOC, just like in the movies.
umbrella is free software, licensed under a BSD-like license.
The latest version of the source code is kept in arch:
