This stacked bar chart displays the percentage distribution of IMDb ratings across six movie genres, with each genre's horizontal segments summing to 100%. Hovering over a segment reveals a tooltip with the exact percentage for that rating level. The visualization is built with D3 v7, using `d3.stack()` to create the stacked data, `d3.scaleOrdinal()` for color mapping, and SVG rectangles for rendering. The chart includes axes, titles, and an interactive tooltip that updates via mouse events.
