This stacked bar chart shows the percentage distribution of IMDb movie ratings across six genres, with each bar segmented into five rating levels from "below 5.0" to "above 8.5." The visualization uses d3.stack() to compute the stacked segments, d3.scaleBand() for genre positioning, and d3.scaleLinear() for the percentage axis. Hovering over any segment displays a tooltip with the exact percentage for that rating level within the selected genre. Colors are assigned via d3.scaleOrdinal() with an array of five categorical colors, and all elements are rendered as SVG.
