Real Example of Google Visualization/Charts with SharePoint

Here is a real example of using SharePoint (WSS or MOSS) with Google Visualizations/Charts. The data your looking at is pool temperature that I've been collecting from a small PLC. The gauges show actual temp (real-time; updates every 2 secs), while the Annotated Timeline shows the history of the time.

The data for the Annotated Timeline is coming from a local MS SQL Express Server which collects the data every 5 minutes. The gauges are real-time connecting directly to the Beckhoff TwinCAT (PLC software) to grab the temp.
