{"version":"1.0","type":"rich","title":"Activity6Task-2","description":"This stacked bar chart visualizes the changing composition of categories A through D across the years 1995-2003. A radio button toggle transitions the rendering between a full stacked bar layout and a narrow, offset view that reveals individual category values. Built with D3 v4, the visualization uses `d3.scaleBand`, `d3.scaleLinear`, and `d3.stack` to process the CSV data, while SVG `rect` elements are animated via `transition` and `attr` calls. The color scale `d3.scaleOrdinal` distinguishes the four categories.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/19dcb0f80d50406f836fd8ab17430436?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
