{"version":"1.0","type":"rich","title":"tutorial2 task 7","description":"This stacked bar chart shows how movie ratings are distributed across genres, with each genre’s bar broken into percentage segments for five rating levels from below 5.0 to above 8.5. Hovering over a bar segment reveals a tooltip with the exact percentage for that rating level within the genre. The chart uses D3 v7’s `d3.stack` to construct the stacked segments, `d3.scaleLinear` and `d3.scaleBand` for positioning, and `d3.scaleOrdinal` for color mapping. Data comes from a CSV file, and the visualization is rendered as SVG.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7efc4dc31a6942b6a5ae85a8b0ff5dc6?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
