title: How can I generate dynamic charts with MySQL data?
body: <p>This is not a question about the names of libraries for making graphs.</p>
  
  <p>I have a project that needed a way to make graphs with data that comes from MySQL.</p>
  
  <p>My question is: A library that provide a <strong>good integration and flexibility with external data</strong>, in this case MySQL data?</p>
  
  <p>I need to calculate averages, make pie charts, change the data in real time, etc.</p>
  
  <p>I would prefer a library that doesn't use JPEG images in final graphs. I would like something like 
  <a href="http://raphaeljs.com/analytics.html" rel="nofollow">http://raphaeljs.com/analytics.html</a> (anyone know if there's MySQL integration for this library?).</p>
  
  <p>I saw the Google Charts API but I don't like the idea of not having library control on my server, and I read that it has limitations.</p>
