Voronoi binning (animated)

Full Screen

Group data points around the largest points.

The recipe is as follows:

1) sort data points according to their sizes (here size = d[3])

2) use top 10% points as Voronoi sites

3) bin all data points according to their Voronoi cell, using voronoi.find(). The binning is rendered by using the Voronoi sites’s color.
