{"version":"1.0","type":"rich","title":"tutorial 2","description":"This stacked bar chart shows how movie ratings are distributed across genres, with each bar representing the percentage of ratings in categories from “below 5.0” to “above 8.5.” Hovering over a segment displays a tooltip with the exact percentage for that rating level within the genre. The visualization uses D3 v7’s `d3.stack` for data stacking, `d3.scaleOrdinal` for color assignment, and `d3.scaleLinear` and `d3.scaleBand` for axes. Data is loaded from a CSV file, and the chart is rendered as SVG with interactive mouse events.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e24d88c335a14fc1956aaea810fddc5b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
