This network diagram visualizes friendship relationships among eight people, with red circular nodes and labeled connections showing who is linked to whom. The layout uses d3.forceSimulation with forceLink, forceManyBody, forceCollide, and forceCenter to position nodes dynamically. Users can drag nodes to rearrange the network, with hover effects highlighting nodes. Data comes from a JSON file containing nodes and link objects, rendered as SVG elements with arrow markers on edges.
