{"version":"1.0","type":"rich","title":"Untitled","description":"This example shows a donut chart that visualizes a small dataset of five categorical values, with each slice colored distinctly and separated by black strokes. The chart uses D3.js version 6, where `d3.pie()` computes the arc angles from the data and `d3.arc()` generates the SVG path geometries with an inner radius creating the donut hole. A color scale via `d3.scaleOrdinal()` maps each category to a unique color, while the SVG rendering is sized and centered within a fixed 450×450 viewport. The slices are semi-transparent and rendered as SVG path elements appended to a grouped container.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f675807779184c0586a9326e929d60a9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
