graphviz是贝尔实验室设计的一个开源的画图工具，它的强大主要体现在“所思即所得"（WYTIWYG，what you think is what you get），这是和office的“所见即所得“（WYSIWYG，what you see is what you get）完全不同的一种方式。它的输入是一个用dot语言 编写的绘图脚本，通过对输入脚本的解析，分析出其中的点，边以及子图，然后根据属性进行绘制。用graphviz来绘图的时候，你的主要工作就是编写dot脚本，你只要关注图中各个点之间的关系就好了，你不需要考虑如何安排各个节点的位置，怎样布局能够使你所绘制的图看起来更美观一些。呵呵，这也许就是”所思即所得“的魅力吧。
What is Graphviz?
Graphviz is open source graph visualization software. Graph visualization is a way of representing structural information as diagrams of abstract graphs and networks. It has important applications in networking, bioinformatics, software engineering, database and web design, machine learning, and in visual interfaces for other technical domains.
Graphviz Site Changes
|
Due to organizational changes, the Graphviz web site will see some modifications in the near future. In particular, it will probably no longer provide binary packages for Windows and Macs. The latter can be obtained via Macports or Home Brew. If someone wants to set up Appveyor for Windows, we would be grateful. |
由于组织改变，站点在未来会有一些修改。特别的是，不再为windows和Mac提供二进制包。
