This example shows a minimal HTML page that combines CSS and JavaScript to render a simple interactive visualization. It uses d3.forceSimulation to run a basic physics-based layout, positioning nodes and links from a small embedded dataset. The code relies on d3 selections for DOM manipulation and updates the SVG in real time as the simulation ticks. The page is intentionally bare, serving as a starting point for exploring React integration with D3, as referenced in the README’s link to a separate React starter template.
