Quick Question
Normally, a scatterplot only allows us to visualize two dimensions - one on the x-axis, and one on the y-axis. In the previous video we were able to show a third dimension on the scatterplot using what attribute?
Explanation
On slide 3, we show the scatterplot from slide 2, but with the number of cylinders shown by the color of the points. This allows us to visualize a third dimension of our data.
