Voronoi decomposition of a 2500-site model. Voronoi cells define the number of neighbours: six for hexagonal cells in red, five for pentagonal cells in blue and seven for heptagonal cells in green. Small black points are for sites over 2500 added in order to avoid difficulties encountered in defining Voronoi cells at the border of a finite set.  [article HTML]
