title: How to get this structure in python?
body: <p>I need to get the following structure in python - 
  [[1,2],[22,37],[92,34]]. I just need to know how to create this structure and how to add elements to it. I wish to plot a scatter plot using these values as described <a href="http://alignedleft.com/tutorials/d3/making-a-scatterplot" rel="nofollow">here</a></p>
