This social network graph visualizes friendships among eight people, with nodes representing individuals and weighted lines showing the strength of their connections, such as the five-way friendship between Diana and Aylin. The visualization uses a force-directed layout powered by D3’s `forceSimulation` with link, ManyBody, and center forces to position nodes, while SVG lines and circles render the graph. Users can drag nodes to explore the network, and the simulation updates positions in real time via the `tick` callback, with data sourced from a CSV file.
