I wrote these scripts that reads clf data out of a logfile. This comes from apache (clf) common log : See what engines have visited this page and how much is online since start of the project! The script need some seconds to read and generate the graphical report ...
Sometimes my script renders colors (random) that seems to be too near to each value or randomizes a missing value - in that case reload the page and let the radomcolorizer render it on a new turn ...
Each color represents a engine and part of the circle, imagine that they are randomized ... (this really works!)
