{"version":"1.0","type":"rich","title":"Circular Bar","description":"A circular bar chart shows how values increase from 2020 to 2040, with each year represented by a colored arc segment radiating from a central point. The chart uses D3.js v5 within a React component, employing `scaleBand` and `scaleLinear` for positioning, `arc()` for segment geometry, and `scaleSequential` with `interpolateRainbow` to color each arc. Rendered as scalable vector graphics (SVG), the visualization includes a red center point and white background. The static input data comes from the `useStaticData` hook, providing year-value pairs.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/33cb282e017942b7ab7871d92f179719?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
