Large data set is causing "handleOverweighted1 is looping too much" error about d3-voronoi-map HOT 1 OPEN

Thanks for using this package, and here is a first quick response.

Unfortunately, I think ~3000 cells is out of the boundaries of this library. The mainstream use case I'm aware of, is for dataviz, where (I guess) the number of cells/data is no more than ~100 cells (at least in this order of magnitude).

To reduce the number of cells, one strategy is to group cells. A legitimate grouping consists on grouping tiny cells in one huge-but-without-important-details cell, usually named 'Others'. You can use this strategy to handle the missing area issue your facing. Maybe, you can try to also use this strategy to introduce more hierarchy levels, and handle those 3000 cells through 30*100 cells.

I'll try to elaborate and give you more details and ideas in another following response.
