This network graph visualizes sales data across the USA, UK, and Canada, showing the relationships between a central "Sales Data" node, country nodes, salespersons, and chocolate products. The d3.v7 library with a force simulation layout positions nodes, with light gray links connecting hierarchical categories. SVG circles and rectangles represent nodes with black borders, while text labels identify each element. The graph uses pinned coordinates for the central node, and the code defines a legend, making the data hierarchy and product-to-salesperson associations explicitly visible.
