title: Building a stacked bar chart from a list within a dictionary matplotlib
body: <p>I have a dictionary which contains a list for each value, for example:</p>
  
  <pre><code>countries = {'NG': [1405, 7392], 'IN': [5862, 9426], 'GB': [11689, 11339], 'ID': [7969, 2987]}
  </code></pre>
  
  <p>Is there a way to build a stacked bar chart from this dictionary using each value as a bit of the stack for each key?</p>
