Geographic map with Tableau

I decided to create a geographic of the number of coal powered power plants still in operation around the United States. As of 2023 there are 213 coal powered power plants all around the US.

The map shows the states with the coal power plants from a range of dark green being the 1 to dark red having 16 power plants.

Texas and Indiana both have 13 coal power plants while Pennsylvania has 16.

I added some clustering to help easily group states by number of power plants they have. There are 4 clusters. 5 if i you included the few states that do not have a coal power plant. It is also intersting to see that Florida has 7 coal power plants in the state.

Adding some text especially on the State to be able to determine how many power plants are located in that state would be incredibly helpful. A legend or key would also be helpful.
