Plotting cash flow ratios

Sometimes, you might want to plot several line plots in one image. However, having too many lines in one plot will make it challenging to read. Making separate facets for every line is more elegant: the figure will look neat and more interpretable.

A pandas DataFrame plot_df has already been loaded for you. It has the columns "Year", "company","cash_flow_to_net_income" and "operating_cash_flow". Seaborn has been loaded with the alias sns.
