title: Dynamic rectangles in Google Maps
body: <p>First I'm pretty new to Javascript, so sorry if my question comes across poorly.</p>
  
  <p>I'm creating an application in Flash to help users calculate their electrical costs. Then I'm taking this figure and write it to an xml file.</p>
  
  <p>Now I'm looking to open a webpage and show a google map, and there is a rectangle drawn over the map which is generated dynamically from the number generated earlier and stored in the xml file.</p>
  
  <p>I'm completely lost as to places to turn on how to achieve this. I've gotten my map on to my page, and it scales 100% as I want it to, but I can't figure out the dynamic rectangle part at all. Any ideas or pointers in the right direction greatly appreciated.</p>
