This visualization displays a simple, cartoon-like smiley face composed of a yellow circular head with a black outline, two black eyes, and a curved mouth. Built with React and D3 v7, the face is rendered as SVG elements, with the mouth generated using the `d3.arc()` path generator. The code defines reusable components for the background circle and eyes, and positions all elements relative to the center of a 960×500 viewport.
