{"version":"1.0","type":"rich","title":"Fork of Activity8_Question2","description":"A stacked bar chart displays population distribution across seven age groups for each US state, using data from a local CSV file. The chart employs D3 v7’s `d3.stack`, `d3.scaleBand`, `d3.scaleLinear`, and `d3.scaleOrdinal` to render SVG rectangles. Hovering over a bar segment triggers a tooltip showing the state, age group, and exact population value, implemented via mouseover and mouseout events with CSS-styled tooltip divs.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/56edfc8b491c450abfec732b9e5a14d4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
