This stacked bar chart shows the percentage distribution of movie rating levels across different genres, demonstrating how genre influences ratings. Each horizontal bar represents a genre, segmented into stacked rating categories totaling 100%. Hovering over a segment reveals the exact percentage for that rating within the genre via a tooltip. Built with d3.v7, the visualization uses `d3.stack()` and `d3.scaleOrdinal` for colors, with data rendering as SVG rectangles.
