Wordle is a tool for generating “word clouds” from text that you provide. The clouds give greater prominence to words that appear more frequently in the source text (ideal for statistical representation). You can tweak your clouds with different fonts, layouts, and color schemes. The images you create with Wordle are yours to use however you like. You can print them out, or save them to the Wordle gallery to share with others.
