{"version":"1.0","type":"rich","title":"groupedbarchart","description":"This interactive grouped bar chart displays the number of students per grades (A, B, C) across different depression levels, using data from a CSV file on student grades and mental health. The visualization uses D3.js v7 and the `d3.scaleBand`, `d3.scaleLinear`, and `d3.axisBottom` APIs for layout. Bars animate in on load via the `transition` method, and hovering reveals a tooltip with exact counts. A clickable legend toggles grade visibility by adjusting bar opacity.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3b620c7e68384e4bba17e83480bc4cb0?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
