This stacked bar chart shows how movie ratings are distributed across genres, with each bar segment representing the percentage of ratings within a specific range, from below 5.0 to above 8.5. Hovering over a segment reveals an exact percentage via a tooltip. The visualization uses d3.stack() to compute the stacked data and d3.scaleOrdinal for color mapping, rendering bars as SVG rectangles. The data is loaded from a CSV file and displayed with d3.axisBottom and d3.axisLeft for the axes.
