This stacked bar chart visualizes sales data for five clothing stores, comparing revenue across three product categories: Cargo, Flannels, and Tee. The horizontal bars display the proportional contribution of each category to total store sales. Built with D3 v7 and rendered as SVG, the visualization uses `d3.stack()` to compute layered series, `d3.scaleBand()` for the categorical y-axis, and `d3.scaleLinear()` for the numerical x-axis. Interactive tooltips on each segment reveal exact category sales values, with the data sourced from the included CSV file.
