This example demonstrates a force-directed network visualization, showing connected nodes arranged through simulated physical forces. The graph renders as SVG circles and lines, with node positions updated dynamically through the simulation. Using D3’s `d3.forceSimulation` and force link/collision/charge forces, the code reads data from a predefined array and updates the SVG elements on each tick. Styling comes from an external stylesheet, while the HTML serves as the container for the D3-managed visualization.
