A yellow smiley face rendered in SVG via React and D3 v7. The face is drawn with two black-outlined circles for eyes, positioned relative to the center using offset constants, and a mouth created with the `d3.arc` path generator, using inner and outer radii and start/end angles. The entire composition is centered on a 960x500 canvas, with all shapes grouped and transformed by a translation. Static parameters define the geometry, and the example demonstrates combining React's declarative JSX structure with D3's arc API for shape generation.
