This represents the diagrams of two large separable permutations, taken uniformly at random: for each \(i\),
there is a dot at coordinates \( (i,\sigma(i))\). It converges towards a Brownian limiting object,
that we called Brownian separable permuton. The same limit arises for uniform random permutations
in a large family of permutation classes.
