Graph of the Day

Today's graphic demonstrates the use of Pandas to grab data from Yahoo!Finance.  The code I wrote uses pandas.io.get_data_yahoo() to grab historical daily data on the S&P 500 index and then generates a simple time series plot.  I went ahead and added the NBER recession bars for good measure. Note the use of a logarithmic scale on the vertical axis. Enjoy!
