This network graph visualizes friendships among eight individuals, using white nodes with labels and directional links with markers. It leverages D3 v6’s `forceSimulation` with `forceLink`, `forceManyBody`, `forceCollide`, and `forceCenter` to position nodes, while drag interactions allow manual rearrangement. The SVG is rendered in React, with data loaded from `data.json`, and hover highlighting is applied via the `focusNode` and `blurNode` functions.
