In this edition of data chatter, we will talk about maps. Maps are excellent devices for telling stories. Think of the maps you see around election times that show which parties won seats where. in fact, the first ever scatter plot - Dr. John Snow’s figure of cholera cases in London, was essentially a map. Or think of the famous map of Napoleon’s invasion of Russia.

And telling stories through maps is an exercise in data science. Data overlaid on maps can help tell really powerful stories. And as we learn in today’s conversation, the process of mapping is no diferent from the process of data science.
