{"version":"1.0","type":"rich","title":"Learn D3.js","description":"This example shows worldwide operating system market share for Android, Windows, and iOS as a labeled pie chart. It renders in SVG using D3 v4, with the `d3.pie` layout generating arc data from hardcoded percentages and `d3.arc` producing the path geometry. A `d3.scaleOrdinal` with `d3.schemeCategory10` assigns colors, while arc centroid labels display each platform and its percentage directly on the chart. The visualization demonstrates basic pie chart construction with group elements and path/text bindings.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a7d61ade0ef04033a0fdcae99be37697?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
