Gerador de nuvem de palavras para trilhos

Question

Existe uma biblioteca Ruby / Rails que eu posso gerar nuvens de palavras (saída deve ser um arquivo de imagem) como em wordle.net ?

Answer 1

Why does it have to be a Ruby/Rails library?

You could use JQCloud, which is a nice JQuery plugin to build word and tag clouds.

Answer 2

Have you looked at heatmap? There's also a nice blog post explaining it:
