This stacked bar chart shows how movie ratings are distributed across six genres, with each bar representing 100% of a genre’s ratings divided into five categories from "below 5.0" to "above 8.5." The visualization makes it clear that genres like Documentary skew toward higher ratings, while Action has a much larger share of low ratings. Built with D3.js v7, the chart uses `d3.stack` and `d3.scaleBand` to position the segments and renders as SVG. Hovering over any segment updates a tooltip displaying the exact percentage, formatted with `d3.format`.
