dot 代码

digraph LinkedList {
    rankdir=LR; // 设置布局方向为从左到右（左侧到右侧）
    node [fontname="Arial", shape=record, style=filled, color="#ffffff", fillcolor="#0077be", fontsize=12, width=1.5, height=0.5];
    edge [fontname="Arial", fontsize=10, color="#333333", arrowsize=0.5];
    // 定义链表节点
    head [label="Head"];
    tail [label="Tail"];
    node1 [label="Node 1 | 5"];
    node2 [label="Node 2 | 3"];
    node3 [label="Node 3 | 8"];
    node4 [label="Node 4 | 2"];
    node5 [label="Node 5 | 9"];
    // 连接链表节点
    head -> node1;
    node1 -> node2;
    node2 -> node3;
    node3 -> node4;
    node4 -> node5;
    node5 -> tail;
}
