This stacked bar chart displays four groups with five categorical segments each, using a harmonious color palette with white strokes between segments. The visualization includes grid lines behind the bars, axes with labels, a legend, and a title. Built with D3.js v7, the code uses d3.stack(), d3.scaleBand(), and d3.scaleLinear() to generate the chart, with data hardcoded in the script and rendered as SVG that fills the browser window.
