Reprezentajca tabel w graphizie :
digraph structs {
node [shape=record];
struct1 [shape=record,label="<f0> left|<f1> mid\ dle|<f2> right"];
struct2 [shape=record,label="<f0> one|<f1> two"];
struct3 [shape=record,label="hello\nworld |{ b |{c|<here> d|e}| f}| g | h"];
struct1 -> struct2;
struct1 -> struct3;
}

Opis ograniczeń podejścia xttml→gv
Tekst w komurakch tabeli nie moze zawierać znaków : <, >, }, {
graviz nie radzi sobie z odpowiednim ustawieniem przy złożonych diagramach (źle rysuje polączenia miedzy tabelami)
