title: How to draw a chart in Google App Engine?
body: <p>I wonder Google App Engine can return a chart ?</p>
  
  <p>What I want is a statistical chart, is there a way for my app in Google App Engine to create a .png chart then return it to the browser ?</p>
  
  <p>For instance when I click a url such as : </p>
  
  <p><a href="http://My_App.appspot.com/Show_App_Stats" rel="nofollow">http://My_App.appspot.com/Show_App_Stats</a></p>
  
  <p>It will show me a graphic chart.</p>
