title: How can I specify the figsize of a graphviz representation of a decision tree?
body: <p>I have a <code>GraphViz</code> representation of a decision tree trained on the iris dataset.</p>
  <pre><code>import graphviz 
  
  dot_data = tree.export_graphviz(clf, out_file=None, 
                       feature_names=iris.feature_names,  
                       class_names=iris.target_names,  
                       filled=True, rounded=True,  
                       special_characters=True)
  
  graph = graphviz.Source(dot_data)
  graph
  </code></pre>
  <p>I am using the above code to generate the <code>GraphViz</code> figure, but it creates a large graph.</p>
  <p>I want to manually control the <code>figzise</code> of this graph. How can I do this?</p>
