Reordering graphs

The graph you built in the last exercise was readable, but it would be easier to understand it at a glance if it was ordered. Let's use some forcats functions to change the graph so it's ordered in descending order of average usefulness from left to right.

The dataset usefulness_by_platform has been loaded for you.
