{"version":"1.0","type":"rich","title":"Untitled","description":"This example shows a donut chart with eight categorical slices, each labeled with a letter from \"a\" to \"h\" and connected to its slice via thin polylines. The chart uses dummy data defined as an object of key-value pairs, with slice colors mapped through `d3.scaleOrdinal` and the `d3.schemeDark2` palette. It computes arc paths using `d3.pie` and `d3.arc`, with a half-radius inner hole, while labels and leader lines are positioned via a second outer arc and centroid calculations. The visualization is rendered as SVG with semi-transparent slices and white stroke separations.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e1e199eb5251469980275bbe80a1d45b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
