  We consider a random planar map $M_n$ which is uniformly distributed over the
class of all rooted q-angulations with n faces. We let $\mathbf{m}_n$ be the
vertex set of $M_n$, which is equipped with the graph distance $d_\mathrm{gr}$.
Both when $q\geq4$ is an even integer and when q=3, there exists a positive
constant $c_q$ such that the rescaled metric spaces
$(\mathbf{m}_n,c_qn^{-1/4}d_\mathrm{gr})$ converge in distribution in the
Gromov-Hausdorff sense, toward a universal limit called the Brownian map. The
particular case of triangulations solves a question of Schramm.
