{"version":"1.0","type":"rich","title":"BURRO VELHO","description":"This visualization, titled \"BURRO VELHO,\" uses a d3-voronoi-treemap to display agricultural production data, breaking down sugarcane varieties (like RB867515) into individual plots with their respective yields and weights. The layout arranges cells within a circular clip region, with each cell's size and color encoding data values. Built with D3 v4 and React, the code leverages `d3.voronoiTreemap`, `d3.hierarchy`, and `d3.scaleLinear`, rendering via SVG. It includes a canvas-based export button using FileSaver.js to save the visualization as a PNG image. The JSON data structure defines hierarchical parent-child relationships for the treemap.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f34768ec19894711887ea5b2fc7c0e68?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
