*About the image - *it's all random points, the text has higher density of them
*A comparison with Fortune's algorithm - *the Julia implementation is somewhat faster than CGAL, and CGAL is faster than Boost Voronoi which uses Fortune's algorithm, see here: http://www.boost.org/doc/libs/1_56_0/libs/polygon/doc/voronoi_benchmark.htm *Treemaps -* I agree it is a very nice plotting addition, it can be implemented once we have weighted generators. It should belong to a different package though...
