Graphviz运行样例代码示例及shape形状

Graphviz样例代码

digraph G{

    size = "5, 5";//图片大小
    main[shape=box];/*形状*/

    main->parse;
    parse->execute;

    main->init[style = dotted];//虚线

    main->cleanup;
    edge[color = green]; // 连接线的颜色

    execute->{make_string; printf}//连接两个

    init->make_string;
    main->printf[style=bold, label="100 times"];//线的 label

    make_string[label = "make a\nstring"]// \n, 这个node的label，注意和上一行的区别
S
    node[shape = box, style = filled, color = ".7.3 1.0"];//一个node的属性

    execute->compare;
}

运行结果：
