Exercise

Adding a hover tool

In this exercise, you'll practice adding a hover tool to drill down into data column values and display more detailed information about each scatter point.

After you're done, experiment with the hover tool and see how it displays the name of the country when your mouse hovers over a point!

The figure and slider have been created for you and are available in the workspace as plot and slider.
