使用gvedit

digraph G{  
    size = "5, 5";//图片大小  
    main[shape=box];/*形状*/  
    main->main;  
    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  
    node[shape = box, style = filled, color = ".7.3 1.0"];//一个node的属性  
    execute->compare;  
}
