{"version":"1.0","type":"rich","title":"Activity 5_Question 3","description":"A stacked bar chart displays regional product sales across four regions, with each bar segmented by product category. The visualization uses D3 v7’s `d3.stack`, `d3.scaleBand`, `d3.scaleLinear`, and `d3.scaleOrdinal` to render SVG rectangles with color-coded segments per product. Data loads from a CSV file via `d3.csv` with `d3.autoType`, and axes are generated using `d3.axisBottom` and `d3.axisLeft`. A legend maps product names to their ordinal color range, annotating each segment’s contribution.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8ceda7da795645f0b06d2f44b82ab0f4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
