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.

doxygen

Doxygen是一种开源跨平台的，以类似JavaDoc风格描述的文档系统，完全支持C、C++、Java、Objective-C和IDL语言，部分支持PHP、C#。注释的语法与Qt-Doc、KDoc和JavaDoc兼容。Doxygen可以从一套归档源文件开始，生成HTML格式的在线类浏览器，或离线的LATEX、RTF参考手册。

安装配置环境变量

Graphviz 安装后需要配置环境变量
将graphviz安装目录下的bin文件夹添加到Path环境变量中：

验证graphviz是否正常

进入windows命令行界面，输入dot -version，然后按回车，如果显示graphviz的相关版本信息，则安装配置成功。
