This visualization displays a stacked horizontal bar chart comparing sales of laptops, phones, and tablets across five stores, with a subtitle referencing a clothing category. The chart uses D3 v7's `d3.stack` and `d3.scaleOrdinal` for color encoding, `d3.axisBottom` and `d3.axisLeft` for axes, and renders as SVG. Interactive tooltips show exact sales values per category and store. Data is loaded from an embedded CSV.
