Have you heard of Wordle? During the presidential campaign it became pretty popular with the press. Wordle creates a visual representation of text. The frequency of a word in the text shows itself in the size of the word. The bigger the word, the more frequently it is used in the source text. The online program allows the user to paste a bunch of text (any text) into a field and then when submitted, in a few seconds, a visual like this one appears.
