This stacked bar chart shows the distribution of IMDb movie ratings across six genres, with each bar segmented into five rating categories. The visualization reveals how genres like Documentary skew toward higher ratings, while Action films cluster at lower scores. Built with D3 v7, the chart uses d3.stack() to compute stacked segments, d3.scaleLinear() for percentages, and d3.scaleBand() for genre categories. Hovering over any segment displays a tooltip showing the exact percentage for that rating level within the genre, using d3.csv() to load the pre-aggregated dataset.
