This example visualizes a social network of six individuals, with nodes grouped by community and linked by weighted connections. The graph shows relationships between people like Noampi, Akruti, and Priya, using light green lines and pink circles. The visualization loads data from a JSON file and uses the older `d3.layout.force` API (not `d3.forceSimulation`) to simulate physics, with node positions updated on tick events. Text labels display names, and users can drag nodes to rearrange the network. The SVG rendering is handled directly through D3 selections.
