Graphviz绘图-FSM状态图

Graphviz绘图 - DOT语言

Graphviz画图只需要两步。第一步创建文本文件并命令为x.dot，输入以下内容：

graph demo {
    "Browser" -- {"Chrome", "Fiefox", "Safari", "..."}
}

第二步，使用命令将文本内容转换为图片。

dot demo.dot -T png -o demo.png

-T表示输出类型，可以指定jpg、gif、svg等等，-o指定输出文件名，不指定则输出到标准输出上。执行上面命令后不出意外则可以看到如下效果。

上面是用dot命令来生产，也可以用Graphviz中包含的其他命令来处理dot文本，比如用下面命令渲染出来的图片排列方式则不一样。

neato demo.dot -T png -o demo.png
