title: convert matrix to image
body: <p>How would I go about going converting a list of lists of ints into a matrix plot in Python?</p>
  
  <p>The example data set is:</p>
  
  <pre><code>[[3, 5, 3, 5, 2, 3, 2, 4, 3, 0, 5, 0, 3, 2],
   [5, 2, 2, 0, 0, 3, 2, 1, 0, 5, 3, 5, 0, 0],
   [2, 5, 3, 1, 1, 3, 3, 0, 0, 5, 4, 4, 3, 3],
   [4, 1, 4, 2, 1, 4, 5, 1, 2, 2, 0, 1, 2, 3],
   [5, 1, 1, 1, 5, 2, 5, 0, 4, 0, 2, 4, 4, 5],
   [5, 1, 0, 4, 5, 5, 4, 1, 3, 3, 1, 1, 0, 1],
   [3, 2, 2, 4, 3, 1, 5, 5, 0, 4, 3, 2, 4, 1],
   [4, 0, 1, 3, 2, 1, 2, 1, 0, 1, 5, 4, 2, 0],
   [2, 0, 4, 0, 4, 5, 1, 2, 1, 0, 3, 4, 3, 1],
   [2, 3, 4, 5, 4, 5, 0, 3, 3, 0, 2, 4, 4, 5],
   [5, 2, 4, 3, 3, 0, 5, 4, 0, 3, 4, 3, 2, 1],
   [3, 0, 4, 4, 4, 1, 4, 1, 3, 5, 1, 2, 1, 1],
   [3, 4, 2, 5, 2, 5, 1, 3, 5, 1, 4, 3, 4, 1],
   [0, 1, 1, 2, 3, 1, 2, 0, 1, 2, 4, 4, 2, 1]]
  </code></pre>
  
  <p>To give you an idea of what I'm looking for, the function MatrixPlot in Mathematica gives me this image for this data set:</p>
