StatVis : some colors from the internet

Hits to x-arn.org wiki are stored into a database. StatVis PHP scripts take
data into this database in order to generate colored visualizations. The
main principle is that an IP address is composed as xxx.xxx.xxx.xxx where
xxx is between 0 and 255, exactly like the value of red, green, or blue in
the RGB space. xxx values also give us the opportunity to take them as
coordinates. Then, for example, counting the number of time the same IP
connects to the website can give us a third value used for a circle width,
and so on.
