   Format: MarkdownItexI did a bit of editing (of Definition and Examples) at [[child's drawing]] (once known as [children's drawing](http://nforum.mathforge.org/discussion/3615/childrens-drawing/)), to emphasize that a child's drawing/dessin d'enfant is not simply a hypermap, but (typically) a hypermap seen as the representation of a Belyi function. I was guided by the presentation in Lando & Zvonkin 2004 ([this paper by Zvonkin](https://www.labri.fr/perso/zvonkin/Research/tesselations.pdf) is also helpful), but apologies if I introduced any mistakes since I'm just learning this stuff.
