A force-directed network diagram visualizes connections between e-commerce entities such as brands, products, cart, and cart items. Five nodes, each labeled with its name, are arranged using d3.forceSimulation with forceManyBody and forceCenter. Curved links between nodes are rendered as SVG paths using a custom linkArc function, with markers indicating link types. Static data is imported from a data.js module, and node positions update on each simulation tick.
