{"version":"1.0","type":"rich","title":"sample 3","description":"Two side-by-side donut charts show grade distribution (A–F) for male and female students, with a tooltip revealing count, depression level, and percentage for each grade. The visualization uses D3 v7’s `d3.pie`, `d3.arc`, and `.join` to render SVG paths and labels. Hovering expands a slice via `arcHover` while an HTML tooltip follows the cursor. Data is hardcoded in JavaScript arrays, and a horizontal legend maps grades to a categorical color scale.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/feade7dde53142c4b543851fa8aaf89f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
