This interactive network graph visualizes the relationships between sales people and products, with node size reflecting total sales and colors distinguishing persons (blue) from products (orange). The visualization uses d3.forceSimulation with forceLink, forceManyBody, forceCenter, and forceCollide to position nodes, while SVG circles and lines render the network. A tooltip appears on mouseover to display node details, and nodes are draggable via d3.drag. The sample data includes sales figures from an Excel spreadsheet, demonstrating a typical sales-product association structure.
