    b -- c;
    d -- e;
    e -- f;
    a -- d;

graph -- adjacency-list data structure

graph {
    rankdir=LR; // Left to Right, instead of Top to Bottom
    a -- { b c d };
    b -- { c e };
    c -- { e f };
    d -- { f g };
    e -- h;
    f -- { h i j g };
    g -- k;
    h -- { o l };
    i -- { l m j };
    t -- z;
}

digraph -- adjacency list data structure

digraph {
a -> {b, c};
b -> {c, a};
