This stacked bar chart shows the percentage distribution of IMDb ratings across six movie genres, with ratings grouped into five levels from below 5.0 to above 8.5. Each bar segment represents a genre's proportion of a rating category, and hovering over a segment displays the exact percentage via a tooltip. The code uses `d3.stack()` to create the stacked data structure from CSV input, `d3.scaleBand()` for the genre axis, and `d3.scaleLinear()` for the percentage scale. The visualization renders as SVG with five color-coded rating categories and includes axis labels and a title.
