This example shows a simple smiley face rendered as an SVG using React and D3. The React component defines a static graphic with a yellow circle for the face, two smaller circles for eyes, and a commented-out reference to a full SVG structure. The code uses React’s `ReactDOM.render` to mount the component into the DOM, while D3 v5 is loaded via a CDN but not actively invoked in the visible script. The rendering approach relies purely on JSX-defined SVG elements, with the face’s dimensions fixed at 960 by 500 pixels in the underlying markup.
