This stacked bar chart visualizes the distribution of IMDb movie ratings across six vehicle-themed genres, showing the proportional share of five rating categories from "below 3.0" to "above 7.0." The chart uses d3.stack() to aggregate the percentage data, d3.scaleBand for the vertical genre axis, and a linear x-scale for the percentage values. Hovering over any segment reveals an exact percentage via a tooltip, while opacity changes highlight the selected bar. The visualization is rendered as SVG with d3.v7, using ordinal color scaling to distinguish rating bands.
