This example displays a yellow smiley face with black-outlined circular eyes and a mouth, drawn as an SVG graphic. The face is centered on a 1000 by 600 pixel canvas, with the head and features positioned using computed coordinates rather than hard-coded values. The visualization uses React to render the SVG elements, while D3’s `arc` function defines the mouth as a full circular path. Eye size, offset, and stroke width are all specified as named constants, demonstrating a modular approach to constructing a static vector illustration.
