{"version":"1.0","type":"rich","title":"Itapipiré","description":"This visualization, titled \"Itapipiré,\" displays a treemap of sugarcane variety weights using a circular layout clipped to a polygon, rendered with SVG. It uses the `d3.voronoiTreemap`, `d3-weighted-voronoi`, and `d3.voronoiMap` plugins on top of D3 v4, with data from a JSON file. The treemap cells are colored by parent category, with legends and a title overlaid. A button triggers PNG export via canvas-toBlob and FileSaver.js, though the core drawing remains SVG-based.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2674d658859043fe97412e6cce0703ab?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
