{"version":"1.0","type":"rich","title":"Pie chart","description":"The visualization displays two interactive pie charts comparing apple and orange counts across five regions, with a toggleable radio interface to switch datasets. Built with D3.js (v5.16.0), it renders an animated SVG donut chart using `d3.pie`, `d3.arc`, and `d3.scaleOrdinal` color scales. Legends appear as colored dots and labels beside the chart. On dataset change, arcs transition smoothly via `transition.attrTween` with interpolation, and a delayed auto-animation replays the arc tweens every two seconds. Data is loaded asynchronously from `data.json` via `d3.json`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/fe01c71143b449d38279924bd3c7545b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
