This network chart visualizes a friend graph of eight people, with pink circular nodes labeled with names and black, arrowed lines showing the relationships between them. The chart uses D3.js force simulation (`d3.forceSimulation`, `d3.forceLink`, `d3.forceManyBody`, `d3.forceCenter`) to position nodes, representing weighted friendships from a local `data.json` file. Nodes are draggable, change stroke on hover, and the SVG rendering includes markers for directed edges.
