{"version":"1.0","type":"rich","title":"Assignment 2 - Stacked Bar","description":"A stacked bar chart displays crash ratings for 24 car makes across five rating levels, with each bar segmented by color to show the proportion of one-to-five-star ratings. Loading CSV data with values between zero and one, the visualization uses D3 v7's `d3.stack()` and `d3.scaleOrdinal` to map rating categories to colors. Hovering over a segment reveals a tooltip with the exact percentage and rating. The SVG renderer includes a legend, axis labels, and a title, styled with custom CSS.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/235680e4d44f4acf892863cbd2197fee?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
