This example uses React.js to render a static smiley face visualization in SVG, building on the “Smiley Face” series. It shows a yellow circle with a thick black stroke for the face, accompanied by two dark eye circles positioned symmetrically around the center. The code explicitly uses React 16.9 production builds via unpkg, and renders the shapes through JSX-style SVG elements (`<circle>`). The rendering approach is purely declarative, with no data source or interactivity, relying on hardcoded coordinates for the face and eyes to demonstrate React’s component-based DOM updates.
