Will I love How Maps Work?

If you draw a map, you have many choices of symbols, colors, types of lines, sizes of characters, and so on. We may think these are just arbitrary choices perpetuated by tradition, but MacEachren successfully shows that we better conceive of those items as solutions to communication problems in a subtle dialogue with the Gestalt requirements of visual perception. Not any symbol will do. The symbols must be fit for minds like ours.

I learned a lot from this visual approach to maps.

Maps and data visualization live in my mind as close cousins: geographical coordinates are often the best way to show where data happens, and the techniques that cartographers have worked out can be adapted to the ways I represent visuals. Maps also have some interpretive advantages over abstract data: San Francisco is always west of Washington, DC. That’s not as true of information graphs, where their respective data points might move around depending on what is being plotted and what the axes are.
