title: Chartkick for Newsletters
body: <p>Is it possible to use <a href="https://github.com/ankane/chartkick" rel="nofollow">Chartkick</a> without rails? I would like to write a ruby script that generates a HTML newsletter which can be send by mail. The output should be a HTML file.</p>
  
  <p>How do I integrate Chartkick into my project and supply it with the data needed?</p>
