This example displays a stacked horizontal bar chart of IMDb movie ratings across six genres, with each bar segmented into five rating ranges from "below 5.0" to "above 8.5" as percentages. The chart uses D3 v7’s `d3.stack` to aggregate genre data, `d3.scaleLinear` for the percentage axis, and `d3.scaleBand` for genre categories. Interactive tooltips appear on hover, showing the exact percentage for each rating segment, while bars reduce opacity for visual feedback.
