A stacked horizontal bar chart displays the distribution of movie ratings across six genres, with each bar segmented into five rating categories from "below 5.0" to "above 8.5." The chart uses D3 v7's `d3.stack()` and `scaleOrdinal` for color mapping, with `scaleLinear` for the x-axis and `scaleBand` for genres. Tooltips appear on mouseover via `d3.select` and `event.pageX`/`pageY`, showing the exact percentage per rating category. Data originates from a local `data.csv` file rendered as SVG.
