title: Alternative to Many Eyes Bubble Chart
body: <p>I am looking for a suitable package (free or otherwise) to duplicate the functionality (mainly in visual department) of IBM's <a href="http://manyeyes.alphaworks.ibm.com/manyeyes/" rel="nofollow noreferrer">Many Eyes Visualizations Bubble Chart</a> in our app. Below attached a screenshot of what I am talking about. Ideally it does the following:</p>
  
  <ol>
  <li>Renders with ether flash or javascript.</li>
  <li>Ability to generate graphs at least once a day. </li>
  <li>Ability to be interactive, i.e. clicking a bubble would be able to do a callback to our javascript</li>
  <li>Looks very similar to the <a href="http://manyeyes.alphaworks.ibm.com/manyeyes/visualizations/twitter-activity-on-the-nyse-and-n-3" rel="nofollow noreferrer">Bubble Chart</a> from Many Eyes (attached below). </li>
  </ol>
  
  <p>Any ideas if such a solution exists?</p>
