dot語言是一種使用代碼描述各種圖形關(guān)系的工具，通常需要安裝Graphviz。
有兩種方法使用dot語言：使用Graphviz，使用plantUML。

• 使用Graphviz
  Graphviz一般是在linux下面運(yùn)行命令
• 使用plantUML
  PlantUml中使用Graphviz/DOT需要以"@startuml"開頭，以"@enduml"結(jié)束。
  可以通過在線PlantUml網(wǎng)站來繪制，非常方便，就避免了在linux下輸入命令

PlantUml中使用dot的例子：

@startdot
digraph graph_name {
    shape1 [shape=box, label="矩形 "];
    shape3 [shape=ellipse, label="橢圓 "];
    shape5 [shape="diamond", label="菱形 "];
    
    shape1:s -> shape3
    shape3 -> shape5
}
@enddot

下面繪制一個(gè)Gitflow的開發(fā)流程：

@startdot
digraph gitflow_workflow {
        "開始" [shape="box"]
        "開始" -> "新的Feature還是新的Bug?"

        "新的Feature還是新的Bug?" [shape="diamond"]
        "新的Feature還是新的Bug?" -> "從dev分支創(chuàng)建Feat-xxx分支" [label = "新Feature"]
        "新的Feature還是新的Bug?" -> "從master中fork分支fixbug-xxx" [label = "新bug"]

        "從master中fork分支fixbug-xxx" [shape="box"]
        "從master中fork分支fixbug-xxx"  -> "在分支fixbug-xxx中修改bug" [label=""]

        "在分支fixbug-xxx中修改bug" [shape="box"]
        "在分支fixbug-xxx中修改bug" -> "分支fixbug-xxx合并到master" [label="bug修改完成"]
        "在分支fixbug-xxx中修改bug" -> "分支fixbug-xxx合并到develop" [label="bug修改完成"]

        "分支fixbug-xxx合并到master" [shape="box"]
        "分支fixbug-xxx合并到master" -> "master分支版本增加" [label=""]

        "分支fixbug-xxx合并到develop" [shape="box"]
        "分支fixbug-xxx合并到develop" -> "完成"

        "master分支版本增加" [shape="box"]
        "master分支版本增加" ->  "完成"
        "完成" [shape="box"]

        "從dev分支創(chuàng)建Feat-xxx分支" [shape="box"]
        "從dev分支創(chuàng)建Feat-xxx分支" -> "開發(fā)Feat-xxx分支" [label=""]

        "開發(fā)Feat-xxx分支" [shape="box"]
        "開發(fā)Feat-xxx分支" -> "合并Feat-xxx分支到dev分支" [label="新特點(diǎn)完成"]
        "合并Feat-xxx分支到dev分支" [shape="box"]
        "合并Feat-xxx分支到dev分支" -> "從dev分支創(chuàng)建release分支"
        "從dev分支創(chuàng)建release分支" [shape="box"]
        "從dev分支創(chuàng)建release分支" -> "release分支新版本發(fā)布"

        "release分支新版本發(fā)布" [shape="box"]
        "release分支新版本發(fā)布" -> "release分支合并到master分支"
        "release分支新版本發(fā)布" -> "release分支合并到dev分支"

        "release分支合并到master分支" [shape="box"]
        "release分支合并到master分支" -> "完成"
        "release分支合并到dev分支" [shape="box"]
        "release分支合并到dev分支"  -> "完成"
}
@enddot
