Danny Dorling has a great TED talk that shows how data can be used to create maps that change how we perceive our world, called “Maps that show us who we are (not just where we are).” The maps convey information about migration, population, demographic change, trade, water, food production, and history, in about a 14 minute video. I think that this video would be a great resource for an introductory class, to show how maps are tools, and are always based on assumptions.
