Scatterplots for multiple pairs of data
In the previous exercise, you saw a numerical representation of the relationship between pairs of data through a correlation matrix. It's also possible to have a graphical representation of those relationships using scatterplots.
Specifically, the relationship between pairs() of time series is represented by a facetted scatterplot of all pairs at once. This is very convenient for a quick comparison between pairs of time series.
In this exercise, you will draw scatterplots of the stock data in my_data from the previous exercise.
