Mapping Senate winners, redux
In the last lesson you created a choropleth map for the Senate results using plot_geo() with a few workarounds. In this exercise, your task is to recreate that map from polygons. That is, create a U.S. map from polygons and fill in states based on the winner of the Senate race.
The senate_map data frame and plotly have already been loaded for you. senate_map contains the information you have seen previously, along with the boundary information needed to draw state polygons.
