This stacked bar chart shows the distribution of Walmart product ratings across six product categories, with each bar divided into five rating percentage segments from "below 5.0" through "above 8.5." The visualization uses d3.stack() to compute the stacked series and d3.scaleOrdinal with a five-color palette to distinguish rating bands. It renders SVG rectangles with d3.scaleLinear for the percentage x-axis and d3.scaleBand for the categorical y-axis, displaying the percentages formatted to two decimals. Interactive tooltips appear on mouseover, showing the exact rating percentage for each segment.
