This stacked bar chart illustrates how the percentage of IMDb ratings varies across six movie genres, such as Documentary and Action, with each bar segmented into five rating brackets from “below 5.0” to “above 8.5.” Built with D3 v7, the visualization uses `d3.stack` to compute the stacked series and `d3.scaleOrdinal` for categorical coloring. Hovering over a segment triggers a custom tooltip that displays the exact percentage for that rating level within the genre, updating via mouse event handlers. The chart relies on SVG rendering and uses `d3.axisBottom` and `d3.scaleBand` for the percentage and genre axes respectively.
