{"version":"1.0","type":"rich","title":"Partition Layout","description":"This visualization shows a hierarchical dataset as a radial partition layout, or sunburst diagram, where each arc segment represents a node’s proportional value. Using D3 v5, the code constructs the layout with `d3.hierarchy`, `d3.partition`, and `d3.arc`, rendering SVG paths. The data is embedded directly in `index.js` rather than read from `data.csv`, with arcs styled via the `styles.css` file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e443ee118b474675bf40f7429c0660e4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
