After looking at the Google Chart API I knew that I had to somehow find a use for this on Moodle so I created the Moodle Meter.

The Moodle meter looks at the weekly stats and displays the results via a Google Chart. The more active a user, the higher the meter reading.

We currently have 4 categories depending on usage. These include casual, moderate, active and expert.
(There are 2 extra ones for admins but students will never attain this).
