Built in feature to highlight countries when JSON is given?


I’m attempting to make a map that showcases political parties based on the number of political party votes per state. I want to pass data into Cesium (State Name) and have that state turn Red or Blue. I’m also using React/Reasium.

Any advice would be appreciated!
