pandas makes plotting quite easy by automating much of the procedure for you. Plotting is handled internally by matplotlib and is publicly accessed through the DataFrame or Series .plot
attribute (which also acts as a method, but we will use the attribute for plotting). When you create a plot in pandas, you will be returned a matplotlib Axes or Figure. You can then use the full power of matplotlib to tweak this plot to your heart's delight.
