轨道的词云发电机

Question

是否有一个Ruby / Rails库，我可以生成Word云（输出应该是图像文件），如 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:
