This visualization shows chocolate product sales across the USA and UK using a vertical hierarchical tree layout, with nodes representing sales representatives, products, and their associated sales values. Node size encodes sales figures, while color distinguishes product categories (Bars, Bites, Other). Built with D3.js v7, it uses the `d3.tree` layout, square link paths, and SVG rectangles for nodes. Interactive tooltips appear on hover, displaying product details or aggregated sales totals for organizational nodes, with smooth transitions applied to highlighting and tooltip visibility.
