This visualization shows a small social network of seven people, with names like Narsimha, Raji, and Priya, represented as purple circles connected by pink links whose thickness reflects interaction weight. The code uses the D3.js v4 library and the `d3.layout.force` API to position nodes and enable dragging. Data comes from a local `data.json` file, and the graph is rendered as an SVG with circles, labels, and lines.
