This example visualizes a small social network with six named nodes and five weighted links, rendered as an SVG force-directed graph. Node labels display names like sandhya, Vidhya, and Prem, with circles and connecting lines styled in red and blue. The layout is computed using d3.layout.force from the older d3.v2 API, while the page also loads d3.v4 without using its newer simulation methods. Graph data is loaded from graphFile.json, and nodes are interactive, supporting click-and-drag repositioning through force.drag.
