Not sure I could get quite what I'm after out of that, but it does look interesting. Switching to an error diffusion algorithm like they use might be better in the long run than my current centroidal voronoi algorithm.

I'm currently running it for all forested biomes with trees spaced at 7km. Over the whole map that's over 150,000 tree symbols eventually.

I've switched my initial seeding from random to a triangular lattice with some jitter. That sped up the seed phase and hopefully won't need as many iterations of the voronoi algorithm. I'm going with 5 iterations this time.
