Voronoi treemaps

Introduction
Voronoi treemaps visualise hierarchical data by recursively partitioning convex polygons using weighted centroidal Voronoi diagrams. The polygon areas are proportional to the relative weights of their corresponding nodes. The animation above shows the algorithm running one iteration at a time for each node of the tree.
Input data instructions
Input data contains 3 columns: the first column is continent/sub-continent, the second column is country/district, and the third column is number of COVID-19 patients.
Note: can accept more column data.
Examples from papers： Tracking the origin of early COVID-19 cases in Canada Fig 1.
