title: Converting a JSON/dictionary into a dataframe
body: <p>I have the following output from a certain API service:</p>
  
  <pre><code>{'node': [{u'A': 300, 'B': u'Ken', u'C': 101901}, {u'A': 400, u'B': u'Miki', u'C': 500001}]}
  </code></pre>
  
  <p>Is this JSON or dictionary?
  How can I convert this to something like this?</p>
  
  <pre><code>A    B    C
  300  ken  601901 
  400  Miki  500001
  </code></pre>
