This stacked bar chart shows the distribution of IMDb movie ratings across six genres, with each bar divided into five rating categories from "below 5.0" to "above 8.5" on a percentage scale. The visualization uses d3.stack() to compute the stacked segments, d3.scaleBand() for the genre categories, and d3.scaleLinear() for the percentage axis. Hovering over a segment reveals the exact percentage for that rating category via a tooltip. Data comes from a CSV file containing genre-by-rating percentage values.
