{"version":"1.0","type":"rich","title":"Activity6_Q4","description":"This stacked bar chart shows the percentage of students receiving grades A, B, C, or D across five school subjects. Each subject’s bar is segmented by grade, colored distinctly, and totals 100%. Built with D3 v7, it loads CSV data via `d3.csv` and stacks values using `d3.stack`. The SVG rendering uses `d3.axisLeft` and `d3.axisBottom` for axes, while a hover tooltip, driven by mouse events, displays each grade’s exact percentage.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f6c6eefb4a404a51a8006b6c71086489?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
