This example uses D3.js (v6) to draw a simple, stylized face on an SVG canvas. A yellow circle forms the head, with two black eyes and rectangular eyebrows positioned symmetrically, and a mouth created using the `d3.arc` path generator. The face is centered within the 960x500 viewport via a translated group element. All shapes are appended directly using D3 selection methods, with hardcoded pixel values for spacing and dimensions.
