{"version":"1.0","type":"rich","title":"Task 8 tutorial 2.1","description":"A stacked bar chart visualizes the distribution of IMDb ratings across movie genres, with each bar divided into five rating brackets from below 5.0 to above 8.5. The chart emphasizes the share of each rating level within genres, allowing comparison of rating patterns. Built with D3 v7, the code uses `d3.stack()` for data stacking, `d3.scaleBand()` for the categorical y-axis, and `d3.scaleLinear()` for the percentage x-axis. Interactive tooltips display exact hovered segment percentages, implemented via mouse event handlers and an HTML overlay styled with CSS.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4cab8234b45c4c8ca0e36cd862ced015?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
