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.
