title: Python to Plot Graphics and Output Vector XY Pairs
body: <p>I need to draw some vector graphics, which is new for me.</p>
  
  <p>Looking for some recommendations for Python modules that can plot vector shapes and output them into a series of XY moves. The shapes will generally be circles and lines and other simple shapes, but will have algorithmic modifiers to thicken, wiggle, or "grunge up" the lines.</p>
  
  <p>I saw a few of the plot libraries (MathGL, matplotlib, pyplot), which all seem to create graphics. Ultimately, I want it to break down the output into a series of XY instructions consisting of a lot of little straight lines.</p>
  
  <p>(I am using Python to output instructions to a digital-to-analog converter controlling the XY movements of a laser.)</p>
  
  <p>Please forgive the blundering of my question. I'll update the question as I am able to formulate it better.</p>
  
  <p>EDIT: On the other hand, maybe this is so simple for those who are move handy with the Maths maybe a PyModule is overkill.  Open to suggestions for cutting up curves into lines.</p>
  
  <p>EDIT2: In the end, I ended up doing my own calculations, but using pyglet to do the vector graphic output. </p>
