This stacked bar chart displays the percentage distribution of IMDb movie ratings across six genres, with each bar segmented into five rating categories from "below 5.0" to "above 8.5." The visualization uses D3 v7 to render an SVG, with genres on the y-axis and percentages on the x-axis. Hovering over a segment reveals a tooltip with the exact percentage for that rating level within the genre. The data is loaded from a CSV file and processed using `d3.stack()` and `d3.map()`.
