A network graph visualizes the relationships between eight individuals, with nodes labeled by name and connected by directed, arrowed links. The layout is determined by a force-directed simulation, using `d3.forceSimulation`, `d3.forceLink`, `d3.forceManyBody`, and `d3.forceCollide`, with nodes rendered as pink circles and blue links. Data comes from a local `networkData.json` file, and the visualization includes interactive dragging via D3's `drag` handler, with hover effects that change the node stroke to green.
