Typographic Map of U.S. Surnames

Typographic map of U.S. surnames from Feb. 2011 National Geographic

Now we know why James Cheshire of Spatial Analysis did a roundup of typographic maps earlier this week (see previous entry): he worked on a typographic map of U.S. surnames that appears in the February 2011 issue of National Geographic. The map shows the top 25 surnames for each state, with type size indicating the number of times each name is used.
