This example visualizes the hierarchical distribution of data related to "Fazenda Arizona," depicting nested categories as a Voronoi treemap. It shows the relative weights of individual data points within colored parent groups, with a computed legend ordering the groups by mean value. The visualization uses the d3-voronoi-treemap library, which builds on d3-weighted-voronoi and d3-hierarchy, to compute the polygonal layout from the `globalEconomyByGDP.json` data. The rendering is done via SVG, with an option to export the current view to a PNG file using canvas-toBlob and FileSaver.
