This example shows a simple yellow face constructed from basic SVG shapes, with two eyes, eyebrows, and a mouth, all centered in a 960 by 500 canvas. D3.js v5 handles the SVG generation and layout, using `select` to target the existing `<svg>` element and `arc` to create the mouth’s curved path. The face’s features are positioned with explicit pixel offsets, and a group element translates the entire composition to the center, demonstrating a straightforward, programmatic approach to drawing with D3.
