A stylized face rendered in red on a green background uses D3.js v5 with SVG primitives. The code builds concentric circles for the head and eyes, then applies the `d3.arc` path generator to create a mouth with an inner and outer radius. All shapes are centered within an SVG of fixed dimensions using a translated group, with eye positions offset via explicit spacing values. The example demonstrates basic D3 shape generation and coordinate transforms without external data.
