title: How I can embed pygal charts in django templates
body: <p>I use pyGal for making charts, but I can't insert them in django templates. 
  It works great, if I try like this in views.py</p>
  
  <pre><code> return HttpResponse(chart.render())
  </code></pre>
  
  <p>But when I make something like this in my template in doesn't work at all</p>
  
  <pre><code> {{chart.render}}
  </code></pre>
