{"version":"1.0","type":"rich","title":"Q2","description":"A horizontal stacked bar chart displays age-group categories (0–10 through 41–50) in a CSV, with each bar divided into four colored segments representing Category1 through Category4. The chart uses D3 v7’s `scaleBand` for vertical positioning, `scaleLinear` for the value axis, and `stack()` to compute segment offsets, with `axisBottom` and `axisLeft` for axes. SVG rectangles render each segment, and mouseover events show tooltip values via `d3.select`. A legend identifies the four category colors.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/64f2837744d74b19a43419cf8039a2a1?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
