Online Data Entry, Dashboard and Charts accessing Google Doc

I am looking at creating a personalized online portal where clients can enter information into a google docs spreadsheet that can then be analyzed and the results graphically displayed and represented with charts and other information on a "dashboard page" (maybe using google chart tools ([login to view URL]) or other JS charts like [login to view URL]). We have already developed the spreadsheets to analyze the data and give data results, and just need to graphically display the data. Items: 1. Personalized Customer Dashboard Webpage (using [login to view URL] or similar) a) Data Entry Form (monthly sales data) which sends data into existing google docs spreadsheet b) Charts displaying results from our analysis ([login to view URL] or [login to view URL] or similar) accessing google docs spreadsheet I am in process of creating the main website using joomla 2.5 with mySql database. Sample Page idea attached. Thanks for your consideration in looking at my project.
