The Brownian map - approximated by a random quadrangulation with 1M faces. The colours of the faces represent closeness centrality in the dual map.
The Brownian map - approximated by a random quadrangulation with 2M faces
The Brownian map - approximated by a random quadrangulation with 4M faces
The Brownian map - approximated by a random quadrangulation with 8M faces
The Brownian map - approximated by a random quadrangulation with 16M faces. The colours of the faces represent height in the dual map.
The Brownian map - approximated by a random quadrangulation with 32M faces.
