title: Jupyter: how to make simple illustrations
body: <p>I am learning to use Jupyter/IPython Notebook as an electronic notebook. Sometimes I need simple illustrations to go along with my calculations, e.g. arrows to represent vector quantities. That's the kind of illustration for which TikZ would be used if we were in Latex. Having tried the TikZ magic extension and failed, I wonder if there's a more native (Python) way to do this. I don't see Matplotlib as the right tool for this sort of thing (correct me if I'm wrong).</p>
  
  <p>If you think TikZ magic is indeed the way to go and I should try to get it to work, then do say so. Thanks.</p>
