London Underground Understood
Harry Beck described the unfortunate person who added a North Arrow to his famous map of the London Underground as a "busybody who had no appreciation of the difference between a map representing geographical reality and a purely geometric straight-line diagram representing connections."
I agree. However, Beck included the Thames on his map, which serves the same purpose as a North Arrow.
By including the Thames, Beck allows his audience to ask questions that lie outside of the London Underground's domain.
My maps use commuting data collected from various Austinites to explore different ways of answering a question, either directly or by leaving the door open to ask new questions.
