GNATS PR Statistics

[Tume Römer]

Hello,

somewhat unrelated to GNATS directly - I am trying to set up a statistics 
webpage for some gnats databases.

I am using the FreeBSD PR statistics scripts as a starting point. 
(http://www.freebsd.org/prstats/index.html
and http://people.freebsd.org/~bsd/prstats/)

Does anyone know which tool has been used to generate the nice barcharts on the 
later page ?
Does anyone know of some alternative statistics generation for GNATS ?

Regards,
