{"version":"1.0","type":"rich","title":"Activity6_Q3","description":"This stacked bar chart visualizes the percentage distribution of grades (A, B, C, D) across five school subjects, with each bar segment color-coded by grade category. The chart uses `d3.csv` to load the data, `d3.stack` to compute cumulative values, and `d3.scaleBand` with `d3.scaleLinear` to map subjects and percentages. Hovering over a segment reveals a tooltip showing the grade and its percentage. SVG rectangles are rendered using D3's `selectAll` and `join` operations, with axes and labels drawn via `d3.axisLeft` and `d3.axisBottom`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/418224c9fb754ca3ab21fede8f1d6237?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
