PicViz - Data Visualization Tool

Picviz is a parallel coordinates[1] plotter which enables easy scripting from various input (tcpdump, syslog, iptables logs, apache logs, etc..) to visualize your data and discover interesting results quickly. This way, you can find in million of events malicious things you were not thinking about and that no regex based program would find for you.
Picviz was greatly enhanced as part of GSoc 2009.
