This example shows a static, SVG-based face composed of large green circle with a blue stroke representing the head, two unevenly sized dark eyes, and a small arc-shaped mouth. A single D3.js `path` element uses the `arc()` generator to draw the mouth, while the circles are defined directly in HTML. The visualization relies on the D3 v7 library, with the `select()` method targeting the SVG for potential manipulation. Only the head, eyes, and mouth are rendered; no interactive behavior or animation is implemented.
