Graphviz is from research.att.com and with this release is open source licensed
software. (I'm looking futher into licensing, tho' before uploading...)
I've been hunting for tools for visualizing build time dependencies and this
looks like one of the first that could meet this need. Web site shows many
cases where this "visualization" can be useful.
Excerpt from GraphViz web site:
graphviz is a set of graph drawing tools for Unix or MS-Windows (win32),
including a web service interface (webdot). Graph drawing addresses the
problem of visualizing structural information by constructing geometric
representations of abstract graphs and networks.
Automatic generation of graph drawings has important applications in key
technologies such as database design, software engineering, VLSI and network
design and visual interfaces in other domains.
