This example shows a force-directed network tree built with the D3.js library (v2), rendered as SVG. It displays nodes labeled with Indian cricket player names, connected by weighted links. The code uses `d3.layout.force()` to simulate physical forces, with circle and text elements for each node, and line elements for links whose stroke-width reflects link weight. Data is loaded from a JSON file, and the force simulation updates node positions and link coordinates on each tick.
