A stacked bar chart displays the percentage distribution of IMDb ratings across six movie genres, with each bar segmented into five rating levels from "below 5.0" to "above 8.5." Hovering over a segment reveals a tooltip showing the exact percentage for that rating level within the genre. The visualization uses d3.stack() to compute stacked data, d3.scaleOrdinal for color encoding, and d3.scaleBand for categorical positioning on the y-axis. The data comes from a CSV file loaded via d3.csv, rendered as SVG elements with mouse event handlers for interactivity.
