A stacked horizontal bar chart visualizes the distribution of IMDb ratings across eight movie genres, with each bar divided into five rating categories from "below 5.0" to "above 8.5." The chart reads values from a CSV file using D3's `d3.stack` and `d3.scaleBand` for the genre axis, while `d3.scaleLinear` handles the percentage axis. Color-coded segments use `d3.scaleOrdinal`, and interactive tooltips appear on mouseover via D3 v7 event handlers, displaying the exact percentage for each rating segment.
