I had a plplot plugin kept secretly that I decided to put in trunk.

This plugin allows you to generate several kind of images, such as PNG. When you are dealing with a huge set of data, this kind of plugin is recommended. Demonstration:
toady@marcadet:~/local/scm/svn/picviz/trunk/samples$ pcv -Tplplot test1.pcv

 < 1> gcw        Gnome Canvas Widget
 < 2> ps         PostScript File (monochrome)
 < 3> psc        PostScript File (color)
 < 4> xfig       Fig file
 < 5> hp7470     HP 7470 Plotter File (HPGL Cartridge, Small Plotter)

By the way, for people who missed it:

And the SVN repository moved away from sourceforge to wallinfire:
$ svn co http://www.wallinfire.net/svn-picviz/trunk picviz

Hum, and the picture of the day: a nmap scan
