This example renders a stylized face with SVG shapes, featuring a yellow circle for the head, two black eyes of differing sizes, and a mouth drawn as an arc path. The code uses D3.js v5 selection methods like `select` and `append` to build the SVG, and the `arc` generator to define the mouth’s curved shape. Positioning relies on the SVG’s width and height attributes for centering, with hardcoded offsets for eye placement, producing a playful, geometric portrait.
