{"version":"1.0","type":"rich","title":"quality area chart","description":"This example shows a pie chart of Spotify Top 50 song genres, with each slice labeled by its percentage of the total and accompanied by a color-coded legend. Using D3 v6, it fetches CSV data from a GitHub gist, aggregates genre counts with `d3.rollup`, and generates arcs via `d3.pie` and `d3.arc`. The SVG rendering applies a `d3.scaleOrdinal` with `d3.schemeSet3` for colors and positions percentage labels using `arc.centroid`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/99b9268d94ff4d6cad767d0a1a31f61a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
