{"version":"1.0","type":"rich","title":"Botafogo","description":"This example uses a Voronoi treemap to visualize farm data from the Fazenda Botafogo dataset, which contains hierarchical groups with weighted leaf nodes. The treemap partitions a circular polygon into colored cells, each representing a data point, with labels and values displayed within. Built with React and D3 v4, it leverages the `d3-voronoi-treemap`, `d3-weighted-voronoi`, and `d3-voronoi-map` plugins to compute the layout. The visualization renders with SVG for shapes and text, and includes a button to export the current view to a PNG file using canvas-toBlob and FileSaver.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9c05a07705d7496790163cb0b8267514?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
