This network graph visualizes friendships among ten footballers, with each yellow node representing a person and directed blue links indicating a “Friend with” relationship. The layout is computed using `d3.forceSimulation` with link, charge, collision, and center forces, and the graph is rendered as SVG. Nodes are interactive and draggable via `d3.drag`, and hovering highlights a node with a thicker border. The data is loaded from a JSON file containing node and link arrays.
