This stacked bar chart shows the percentage of IMDb movie ratings within each genre, with each bar segment representing a rating band from below 5.0 to above 8.5. The visualization highlights how genres like Documentary skew toward higher ratings, while Action films have a larger share of low scores. The chart is rendered as SVG with D3 v7, using `d3.stack` to compute the stacked segments, `d3.scaleOrdinal` for the color scheme, and `d3.axisBottom` and `d3.axisLeft` for the axes. Hovering over a segment triggers a tooltip that displays the exact percentage value. The data is loaded from a CSV file containing genre and rating-level proportions.
