title: JavaScript Charts API: Flot jQuery Plugin OR Google Visualization?
body: <p>I am looking for a charts library to be displayed on a website. I will use intensively this library (for area, line and bar charts mainly), so I prefer to secure my choice before starting implementing.</p>
  
  <p>The list of website chart libraries that I have initially considered are:</p>
  
  <ul>
  <li><a href="http://www.liquidx.net/plotkit/" rel="noreferrer">Plotkit</a></li>
  <li><a href="http://www.ejschart.com/" rel="noreferrer">Emprise JS Charts</a></li>
  <li><a href="http://omnipotent.net/jquery.sparkline/" rel="noreferrer">Sparkline</a> </li>
  <li><a href="http://www.deensoft.com/lab/protochart/index.php" rel="noreferrer">Protochart</a></li>
  <li><a href="http://g.raphaeljs.com/yael" rel="noreferrer">gRaphael</a> </li>
  <li><a href="http://bluff.jcoglan.com/" rel="noreferrer">Bluff</a></li>
  <li><a href="http://developer.yahoo.com/yui/charts/" rel="noreferrer">YUI Charts</a>: </li>
  </ul>
  
  <p>However after some researches on this forum and investigations on the web, I have reduced my candidate list to these two libraries:</p>
  
  <ol>
  <li><a href="http://code.google.com/p/flot/" rel="noreferrer">Flot jQuery plugin</a> </li>
  <li><a href="http://code.google.com/apis/visualization/" rel="noreferrer">Google Visualization</a>  </li>
  </ol>
  
  <p>Which one do you advise me to use and why (if you have worked with one or two of them, please tell me your feedback)?</p>
  
  <p>How do they compare one to each other regarding ease of use, performance and features?</p>
  
  <p>Thank you</p>
  
  <p>EDIT: Based-Flash Chart libraries were not eligible with my constraints</p>
