These days Choropleth has gained popularity — specially tile grid map. In this article, we are going to create a square Choropleth map which has become very popular nowadays. These are maps, where areas are shaded according to a prearranged key, each shading or color type representing a range of values. In this version, the map areas are reduced to a uniform size and shape (typically a square) and the tiles are arranged to roughly approximate their real-world geographic locations. Don’t you think, this is a great idea as it allows for a smaller national map that still preserves the overall location & region and maximizes overall information?
