title: Python Heatmap from csv
body: <p>I've seen some examples on how to do a heatmap but I crashed my head against the wall more than once, since I don't really know how my .csv file has to look like to be usable for creation of a heat map. The one I'm trying to visualize looks like the following:

  <p>I've seen solutions with numpy and matplotlib that looked really nice, but I always failed at the conversion of my .csv to a usable format. If anyone could show/tell me where/how to make it usable, that'd be great.</p>
