node-d3-quadtree - 1.0.3-2 main

A quadtree recursively partitions two-dimensional space into squares, dividing
each square into four equally-sized squares. Each distinct point exists in a
unique leaf node; coincident points are represented by a linked list.
.
Quadtrees can accelerate various spatial operations, such as the Barnes–Hut
approximation for computing many-body forces, collision detection, and
searching for nearby points.
