A smiling face is drawn as a static SVG graphic, centered on a yellow circular face with black outlines, two black eyes, and a stylized mouth arc. The visualization uses React to render the SVG elements and the D3.js `arc` function to define the mouth's path geometry. Data is not loaded; instead, all shapes are hand-coded with fixed pixel coordinates and radii, with the D3 `arc` method specifying the mouth's inner and outer radii and angular range. The rendering relies on SVG primitives within a 960 by 500 viewport.
