plotOptions.networkgraph.layoutAlgorithm.approximation

Approximation used to calculate repulsive forces affecting nodes. By default, when calculating net force, nodes are compared against each other, which gives O(N^2) complexity. Using Barnes-Hut approximation, we decrease this to O(N log N), but the resulting graph will have different layout. Barnes-Hut approximation divides space into rectangles via quad tree, where forces exerted on nodes are calculated directly for nearby cells, and for all others, cells are treated as a separate node with center of mass.
