Visualizing predicted values
When dealing with time series data, it's useful to visualize model predictions on top of the "actual" values that are used to test the model.
In this exercise, after splitting the data (stored in the variables X and y) into training and test sets, you'll build a model and then visualize the model's predictions on top
of the testing data in order to estimate the model's performance.
