{"version":"1.0","type":"rich","title":"Activity 8_2","description":"This stacked bar chart visualizes the impact of movie genre on rating distributions, showing the percentage of each rating level within genres. It uses D3 v7’s `d3.stack()` and `d3.scaleOrdinal()` to construct the stacked bars, with `d3.scaleBand()` for genre positioning and `d3.scaleLinear()` for the percentage axis. Mouseover events trigger tooltips displaying precise percentages for each rating segment. The SVG render uses data from a CSV file containing student test scores and demographic information.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/76ca643ba7f64e03a0fdc43bfb3a630b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
