{"version":"1.0","type":"rich","title":"ATR","description":"This visualization uses a Voronoi treemap to display hierarchical data, with each cell representing a data point and its size proportional to a weight value. The code leverages the `d3-voronoi-treemap` plugin along with `d3-weighted-voronoi` and `d3-voronoi-map` to compute the layout, while D3 v4 handles the SVG rendering. The example remakes a chart about the costs of being fat, using a JSON dataset with cluster groups and numeric codes. It includes a button to export the visualization to a PNG via the canvas-toBlob library and FileSaver.js.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/51cedf18a61f48cd912b0760a703c6e8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
