A smiley face rendered in yellow with black outlines looks askance through two offset eyes and a curved mouth. Built with React components and D3's `arc` generator, the SVG circles and path define the face’s features. The code uses static, hard-coded values for dimensions and positions, with D3 v6 handling the mouth’s arc calculation. The visualization is a playful, minimalist exercise in combining React’s declarative structure with D3 geometry.
