This example renders Santa Claus’s face as a stylized SVG composition using React and D3 v6. It shows a circular face with eyes, iris, pupils, nose, ears, a curved mouth via `arc()`, and a white beard path, alongside a red hat and pom-pom shapes. The code imports `select` and `arc` from D3, defines geometric constants for radii and offsets, and constructs nested `<g>` groups with circles and paths. The rendering relies on SVG elements within a React component, with styling defined in CSS.
