a [label="Foo"];
b [shape=box];
c [shape=egg];
d [shape=point];
e [shape=circle];
r [shape=triangle];
f [shape=plaintext]
g [shape=diamond]
h [shape=trapezium]
i [shape=parallelogram]
j [shape=house]
k [shape=pentagon]
l [shape=hexagon]
m [shape=septagon]
n [shape=octagon]
o [shape=doublecircle]
p [shape=doubleoctagon]
q [shape=tripleoctagon]
a->o[label="sdfddd\ndfdfdf"]
o->p->q;
a->l->m->n;
a->i->j->k;
a->f->g->h;
a -> b ->e[color=blue];
a->c[label="h y"];
c -> d->r[style=dotted];
