This example renders a smiling face as an interactive-less SVG composition using React to define reusable visual components and D3's `arc` generator to draw the mouth. The smiley consists of two black eyes with wheat-colored pupils, a red nose, and a pink circular head with a curved mouth path. All shapes are positioned within an SVG canvas, mirroring the classic smiley structure but with custom colors and styling applied through CSS classes. The code demonstrates integrating D3’s geometric path utilities with React’s component-based rendering approach.
