A yellow smiley face with black outlines is rendered in SVG, centered on a 960 by 500 canvas. The face’s size, stroke width, eye placement, and mouth are all controlled by props. Built with React and D3 v5, the example demonstrates modular component structure by splitting the face into separate files for the background circle, eyes, mouth, and container, using ES6 modules and React Fragments. D3’s `arc` generator creates the mouth path, while React handles the SVG element structure.
