Transforming data into the time series format
We will start by understanding how to convert a sequence of observations into time series data and visualize it. We will use a library called pandas to analyze time series data. Make sure that you install pandas before you proceed further. You can find the installation instructions at http://pandas.pydata.org/pandas-docs/stable/install.html.
