Graphvis
  • 以下の内容で、sample.dot を作成
digraph {
    rankdir=LR;
    
    0 [ shape = doublecircle, label = "0 \n generate=5" ];
    1 [ shape = doublecircle, label = "1 \n generate=2" ];
    3 [ shape = rect, label = "3 \n consume=2" ];
    4 [ shape = rect, label = "4 \n consume=1" ];
    5 [ shape = rect, label = "5 \n consume=4" ];
    
    0 -> 0 [ label = "1" ];
    0 -> 1 [ label = "2" ];
    0 -> 2 [ label = "5" ];
    1 -> 0 [ label = "1" ];
    1 -> 2 [ label = "8" ];
    2 -> 3 [ label = "1" ];
    2 -> 4 [ label = "7" ];
    3 -> 5 [ label = "2" ];
    3 -> 6 [ label = "5" ];
    4 -> 2 [ label = "7" ];
    4 -> 3 [ label = "5" ];
    4 -> 5 [ label = "1" ];
    6 -> 0 [ label = "5" ];
}
  • 以下のコマンドを入力
$ dot -Tpng sample.dot -o sample.png
  • 画像 sample.png が出力される
