Mapping Senate winners

There were 33 Senate seats on the ballot in the 2018 midterms (plus two special elections that we'll ignore in this exercise). Your task is to create a choropleth map using the winning candidate's political party to color in the state.

This task requires you to map a factor to the fill color. However, the z aesthetic expects a numeric variable. An easy work around is to convert party to a numeric variable via as.numeric(party) and then manually specify the desired colors in add_trace(). Additionally, the colorbar is no longer very useful, and can be removed by adding the layer hide_colorbar().

The senate_winners data frame and plotly have already been loaded for you.

Create a choropleth map of the where the color of the state represents the winning party.
In add_trace(), manually specify the colors "dodgerblue", "mediumseagreen", and "tomato" (in that order).
Complete the hover info text with the appropriate column names.
