Yes, choropleth maps can incorporate various shapes for depicting different colors on the map. The shapes can vary from squares, circles, and hexagons to more complex shapes such as custom polygons. The choice of the shape depends on the data being represented and the goals of the mapmaker. For example, hexagonal tiles are becoming increasingly popular for choropleth maps as they allow for more efficient use of space and can help reduce visual bias in the map.
