（二）Graphivz 簡單結構圖及子圖

一、簡單數據結構圖

digraph structs {    node [shape=record];    struct1 [shape=record,label="<f0> left|<f1> mid\ dle|<f2> right"];    //record圖形，三個屬性f0,f1,f2    struct2 [shape=record,label="<f0> one|<f1> two"];    struct3 [shape=record,label="hello\nworld |{ b |{c|<here> d|e}| f}| g | h"];    struct1 -> struct2:f1;    //指向struct2 的f1屬性    struct1 -> struct3;}

二、子圖

digraph g {    subgraph cluster0 {        //我是一個子圖，subgraph定義了我，        node[style = filled, color = white];        //我之內的節點都是這種樣式        style = filled;        //我的樣式是填充        color = lightgrey;        //我的顏色        a0->a1->a2->a3;        label = "prcess #1"        //我的標題    }    subgraph cluster1 {        //我也是一個子圖        node[style = filled];        b0->b1->b2->b3;        label = "process #2";        color = blue;    }             }

畫一個子圖就是subgraph cluster#，必須有cluster 前綴。
