A stacked bar chart displays sales totals for Clothing, Equipment, and Accessories across five named stores, using distinct colors for each category. The visualization relies on D3 v7’s `d3.stack()` to layer the data series, with `d3.scaleBand` positioning bars and `d3.scaleLinear` mapping values to the y-axis. SVG rectangles render each stack segment, while rotated bottom-axis labels and a custom HTML/CSS legend improve readability. The CSV data is embedded directly in the JavaScript, and the chart is generated entirely client-side.
