What is a map, even? A cartographer might answer that question with a focus on the geospatial, whereas an information designer might focus on the conceptual. In this episode, author Carissa Carter offers a definition of “map” in her new book The Secret Language of Maps that is somehow broad and very specific at the same time, encompassing any visualization that conveys its message through spatial means. She shares a few lessons from her book on how to deconstruct maps, examining the pieces in detail to give us a better understanding at how to put them back together and use them to understand the people and phenomena they represent.
