This stacked bar chart shows how rating levels distribute across six lifestyle categories, with each bar divided into segments representing the percentage of ratings below 5.0, 5.0–6.5, 6.5–7.5, 7.5–8.5, and above 8.5, summing to 100% per category. The chart uses d3.stack() to compute the stacked series, d3.scaleBand() for the categorical y-axis, and d3.scaleLinear() for the percentage x-axis. Hover interactions trigger a custom tooltip that displays the exact percentage for each rating segment. Data comes from a CSV file with pre-aggregated proportions, and the visualization is rendered as SVG using D3 v7.
