Counting problems for maps (ribbon graphs) and hypermaps (Grothendieck's dessins) will be discussed. It will be shown that the generating functions associated with map and hypermap count satisfy a number of remarkable integrability properties, like Virasoro constraints, evolution equation, KP hierarchy and topological recursion in the sense of Eynard-Orantin.
