title: Best analytics/data visualization library for MongoDB
body: <p>In your opinion, what is the best library to crunch data AND build the web based reports in this context:</p>
  
  <ul>
  <li>Data: documents in MongoDB, less than 1M documents, time is a key dimension in the data</li>
  <li>Framework: Rails (but I'm opened to others)</li>
  </ul>
  
  <p>There are tons of Javascript data visualization libraries, but ideally I'm looking for something that integrates "off-the-shelf" with MongoDB, and that uses modern technologies (HTML5) vs. old (Flash).</p>
  
  <p>If I don't find anything MongoDB specific, I might go with either Google Chart or D3.js, which looks awesome but maybe too "young".</p>
