This example presents a social network graph of Bengaluru locations, where colored nodes represent places like Silk Board Junction and Majestic, and blue links show connections between them with stroke width proportional to link weight. It uses the D3.js v2 force layout (`d3.layout.force`) to simulate node positioning, with drag interaction enabled via `force.drag`. The SVG rendering reads node and link data from an external `data.json` file, displaying each location’s name as text alongside a circular marker. The visualization updates positions on each tick of the force simulation.
