328250 Google Maps - Heat Map

Hi, We have a large data set, and would like our data displayed on google as a heat map. The system should excute a sql query to grab the daily stats from our database. (We can send you the SQL statement to use). Then the system should take the results, and on a daily basis add it to the heatmap. We should be able to enter a date range so we can see how the data look on different data range. The system should also have a time line type of scroller, that will make it easier to scroll on to different days (ie, on every click the next days data is displayed). If you have done any google maps api integration could you send me some live examples. Kind Regards Irfan
