This stacked bar chart displays clothing sales across five stores, breaking down revenue into jeans, t-shirts, and shirts. Using D3 v7, the code loads data from a CSV file and applies the `d3.stack()` function to generate segments, with an ordinal color scale distinguishing product categories. Horizontal bars are rendered as SVG rectangles scaled by `d3.scaleLinear` for the x-axis and `d3.scaleBand` for store names. Interactive tooltips appear on mouseover, showing precise sales figures for each category per store.
