Which pairs of letters are used the most in different languages? The above visualization shows the number of times each pair of letters appears in Cervantes’ Don Quixote, with the size of each bubble proportional to the number of times it appears in the book. The project has interesting implications for typography that can be designed for specific books and languages.
Check out the dynamic version here, along with examples from other texts in English, German, Dutch, and Catalan.
