smile face with react
This example renders a smiling face as an SVG graphic using React components and D3’s `arc` generator for the mouth. The face consists of a yellow circle, two black eyes with white highlights, a curved mouth path, and additional gold and white elliptical details, all positioned via SVG transforms. D3 v7 provides the arc shape, while React 17 manages the component hierarchy. The drawing is static, with dimensions and offsets hardcoded in JavaScript, and rendered into the DOM via `ReactDOM.render`.
