This network graph visualizes relationships between eight people, with nodes representing individuals and links showing connections between them. The graph uses physics-based force-directed layout through `d3.forceSimulation`, combining forces from `d3.forceLink`, `d3.forceManyBody`, `d3.forceCollide`, and `d3.forceCenter` to position nodes. Interactive dragging is enabled via `d3.drag`, allowing users to manually reposition nodes. The SVG rendering includes arrow markers on links via the `defs` element, and node hover effects are implemented with CSS classes. Data comes from a JSON file containing node names and link relationships.
