Avoid misinterpretation in scatter plots.
Great for visualizing data as scatter-like button plot, where points would otherwise be displayed upon another.
Visually overlapping disks are iteratively combined on a weighted basis until no more intersect.
In mathematical terms, each merged disk has coordinates and volume given by
where each and , are the coordinates and volumes of all disks within a cluster. The clusters are the connected components within the graph where two vertices are neighbored if their plotted disks visually overlap. This process is repeated until no more disks overlap.
Avoid quadratic complexity.
The algorithm should scale as in the number of points N. Tested up to 200.000 points.
