title: Python pygal rendering to screen
body: <p>I am following a book (Python Crash Course) and I am not able to see the plot. This is my code</p>
  
  <pre><code>from pygal.maps.world import World
  wm  = World()
  wm.title = "Population of Countries in North America"
  wm.add('North America', { 'ca':34126000, 'us': 309349000, 'mx': 113423000})
  #wm.render_to_file('na_populations.svg')
  wm.render()
  </code></pre>
  
  <p>Any ideas on how to fix this? I am trying this out on SublimeText. </p>
