title: What is the best graphing/charting toolset to use for creating Google Analytics type graphs?
body: <p>Given a Rails application on the server, what is the best charting/graphing solution for displaying dynamic, database driven charts/graph on a web page such as those available in Google Analytics. </p>
  
  <p>An optimal solution would include components that can speak JSON back-and-forth with the Rails application via AJAX.</p>
  
  <p>Thanks!</p>
