This stacked bar chart shows the distribution of IMDb ratings across six movie genres, with each bar representing the percentage of films falling into five rating bands from "Below 5.0" to "Above 8.5." Hovering over a segment displays an exact percentage in a tooltip. The visualization uses D3 v7’s `d3.stack()` to aggregate the data, `d3.scaleBand()` for the categorical genre axis, and `d3.scaleLinear()` for the numeric percentage axis, rendering as SVG with interactive mouse events.
