S&P 500 company correlation table - Python Programming for Finance p. 8

Hello and welcome to part 8 of the Python for Finance tutorial series. In the previous tutorial, we showed how to combine all of the daily pricing data for the S&P 500 companies. In this tutorial, we're going to see if we can find any interesting correlation data. To do this, we'd like to visualize it, since it's a lot of data. We're going to use Matplotlib for this, along with Numpy.
