{"version":"1.0","type":"rich","title":"Cor por idade","description":"This example visualizes agricultural land distribution by age group using a Voronoi treemap, rendered as colored cells within a circular boundary. The layout uses the `d3.voronoiTreemap` plugin to partition hierarchical data from `globalEconomyByGDP.json`, with each cell sized by weight and labeled with age categories. The code sorts legend entries by computed mean productivity values, draws the treemap via SVG, and includes a button that exports the visualization to a PNG using `canvas-toBlob.js` and `FileSaver.js`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5a8088e8c35d4e439c44897ae268d523?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
