This example demonstrates how to construct a cartoon face using D3.js v5, with each facial feature—eyes, nose, and mouth—drawn as separate SVG shapes. The code uses `d3.forceSimulation` to position the features dynamically, creating a playful, animated arrangement. The page renders to an SVG canvas of 960 by 500 pixels, with styles handled in a separate CSS file. The face emerges from the interaction of simulated forces, showcasing how D3's physics-based layout can organize visual elements.
