I've implemented a word cloud generator called WordCloud.jl in Julia language. A brief description about its algorithm can be found here. Unlike most other implementations, I designed it based on gradient optimization. It’s a non-greedy algorithm in which words can be further moved after they are positioned. Thus the size of the words and the shape and size of the background mask can be kept unchanged in the generation process. This makes the outputs more accurate and easy to customize. Furthermore, we can also generate some fancy outputs like these: Comparison of Obama's and Trump's inaugural address and Wikipedia: Julia

我正在研究WordCram，一个用于制作词云的处理库。它受到Wordle的很大影响，并被上面链接的相同的PDF aeby告知。它为你处理碰撞检测，让你专注于你想要的文字布局，颜色，旋转等。

这是一个非常好的javascript代码，来自Jason Davies，它使用了d3。你甚至可以使用web字体。

这里看到我像云一样实现Wordle。 它使用相同的螺旋算法和四叉树数据结构。

我创建了一个Silverlight组件，它使用Jonathan在这里建议的算法。源代码和示例项目都可以在我的博客上找到:

我的云可以让你根据不同的权重为单词着色和大小，它支持单词选择(从坐标)和选中的单词高亮显示。源代码是您的，您可以根据需要使用。
