{"version":"1.0","type":"rich","title":"Fork of Donut Chart","description":"This visualization uses an arc diagram to display the hierarchical composition of the Observable Flare dataset as a donut chart. Each ring segment represents a node, colored by its top-level category, with labels for smaller divisions. The chart is built with D3 v5’s `d3.partition` layout and `d3.arc` generator, rendering SVG paths and text elements. It loads data from the `@observablehq/flare` module and uses `d3.scaleOrdinal` with an interpolated rainbow palette for coloring.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ee3964009e054d3d9186c820fd38bd2f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
