ImmerStat is a plugin I wrote over the weekend after getting tired of the Flash applet that displays statistics for the WordPress.com Stats plugin. It’s overkill when I just want to get a general idea of where I’m sitting at the moment stats-wise. ImmerStat gets rid of the WordPress.com Stats widget from the Dashboard and replaces it with an ever-present .PNG in the top-right corner of the admin screen.
The statistics are pulled using the same functions that the WordPress.com Stats plugin uses and are cached for 5 minutes, as are all stats from the plugin. The graphic is created on the fly using the Google Charts API. The plugin just build the URL and sends it to the browser. Colors, timespan, and Google Charts parameters are all completely configurable using filter hooks.
WordPress 2.5 is the primary version supported. Previous versions should work, but have not been tested.

Cool! Sounds like a good plugin!
Cool integration with Google Charts API.
Keep the good work.
