Seems like a chart, not a map.
For map enthusiasts out there — you know who you are — this is a new kind of chart we are calling a Voronoi treemap map, based on the work of two visualization researchers, Michael Balzer and Oliver Deussen.
The Times has published treemaps before, as when it described how financial companies lost value during the financial crisis; it has also published Voronoi treemaps before, notably to describe inflation in 2008. But this is the first Voronoi treemap map, which uses geographic shapes as the boundaries in a Voronoi treemap.
One drawback of this technique, however, is that it’s not always possible to make each shape exactly the right size; some small values are slightly larger or smaller than they should be. (It’s either that or put holes in the map.)
true. map was not captured. Here is a snapclip of it.
Voronoi Treemap Maps is something I arrived at several years ago also for something I've been working on. I add several more things to it for my solution. This seems to be where the nested map implementation came from which is what led to the map above:

What a cool concept, and great for visualization!
