title: Combine a graph with a drawing made with turtle module
body: <p>I need to draw something using the turtle module on the same canvas on which a graph would be plotted.</p>
  
  <p>I've thought about using matplotlib to make a graph, but I need to later draw something with turtle on that graph. I could draw both the graph and the other things with turtle, but that is much more complicated.</p>
  
  <p>Can anyone think of a better way?</p>
