Voronoi diagrams of orders 1, 2, 4, and 8 of a uniformly distributed (x, y) toy seed points set where x ∈ [ − 1.5, 1.5] and y ∈ [ − 1.5, 1.5]. Each panel only shows x ∈ [ − 1, 1],y ∈ [ − 1, 1] to avoid window effects. The toy set is the same for each panel, but the order is different (n = 1, 2, 4, and 8, shown on top of each panel). The seed points are shown as small black circles, while each cell is randomly colored in the background and their borders delimited by solid black lines.
