This stacked bar chart shows sales by product category (Clothing, Equipment, Accessories) across five store locations, with each bar segment proportional to category revenue. Built with D3 v7, it uses `d3.stack()` to process the CSV data and `d3.scaleBand` and `d3.scaleLinear` for the axes. The SVG rendering includes interactive tooltips on mouseover and a custom color scale using `d3.scaleOrdinal`. The dataset comes from an embedded CSV file, and the chart features labeled axes and a legend.
