This example displays a small social network graph of named individuals, with orange circular nodes connected by red links whose thickness indicates a weight value between connections. The visualization is built with React and rendered as SVG using D3.js version 4, specifically employing the `d3.layout.force` API to simulate the layout physics, including gravity, distance, and charge parameters. Node positions update continuously during the force simulation’s tick events, while labels and drag interactions are handled through the standard D3 selection and `force.drag` methods.
