  A tree, embedded into plane, is a dessin d'enfant and its Belyi function is a
polynomial --- Shabat polynomial. The Zapponi form of this polynomial is
unique, so we can correspond to an embedded tree the Julia set of its
Shabat-Zapponi polynomial. In this purely experimental work we study relations
between the form of a tree and properties (form, connectedness, Hausdorff
dimension) of its Julia set.
