title: networkx: how to control radius of circular_layout()?
body: <p>I'm working with random graphs (created with <code>nx.gnm_random_graph()</code>). The only neat way to lay these out is with a circular layout. Networkx provides at least two equivalent ways to do this but I don't know how to control the radius of the circle with either of them:</p>
  
  <pre><code>nx.draw_networkx(G, pos=nx.circular_layout(G))
  nx.draw_circular(G) 
  </code></pre>
  
  <p>Does anybody know how to increase the radius/diameter so the nodes are not so squashed together ?</p>
  
  <p>Thanks,
  Paul</p>
