title: Graphviz not displaying PNG in Python Idle
body: <p>I am using the following code to display in image in Python IDLE but no luck.</p>
  
  <pre><code>import pydot
  import graphviz
  import os
  
  G = pydot.Dot(graph_type = 'digraph')
  node = pydot.Node('Name')
  G.add_node(node)
  from IPython.display import Image, display
  im = Image(G.create_png())
  display(im)
  </code></pre>
  
  <p>Each time I run the code, it returns the following instead of displaying a png.</p>
  
  <pre><code>&lt;IPython.core.display.Image object&gt;
  </code></pre>
  
  <p>Could someone point out whats wrong here?</p>
  
  <p>Thank you.</p>
