This stacked bar chart shows the distribution of IMDb ratings across six movie genres, where each bar is segmented into five rating categories from "below 5.0" to "above 8.5." Using D3.js v7 with an SVG rendering, the code employs `d3.stack()` to compute the stacked segments, `d3.scaleOrdinal()` for color mapping, and `d3.scaleBand()` for the categorical genre axis. Interactive tooltips display the exact percentage for each genre-rating combination on mouseover, while the data is loaded from a CSV file with precomputed proportions.
