Charting your log data lately?

I came across this cool howTo over at Linux Planet that shows an example of how to easily create graphs of log data.  The article gives a good pratical example of pulling some data on TLD's that have bounced bad e-mail.  The tool he uses is python with a graphing library that can do output as HTML or several other formats.  It's a great easy way to show people when problems are happening.

It really helps to put the link to the Howto when you post about it.  Here it is.  Thanks to Octman for pointing it out.
