{"version":"1.0","type":"rich","title":"Fork of grades vs sleep patterns","description":"This example visualizes student grade distributions across sleep patterns using interactive pie, bar, and grouped bar charts. The SVG-based visualization uses D3 v7 APIs including `d3.rollup` for data aggregation, `d3.pie` and `d3.arc` for the donut chart, and `d3.scaleBand` with `d3.axisBottom` for bar rendering. Users switch between chart types via buttons, while mouseover events trigger tooltips displaying category counts. Data comes from a CSV file containing student grades and mental health information.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6aae423f829042ae8121649abb83a1ad?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
