Smiley Face
A yellow smiley face rendered as an SVG circle with two smaller black circles for eyes sits centered on a 960×500 canvas. The page loads React 16.9 and ReactDOM 17.0.2 from unpkg, though the visualization itself uses only raw SVG elements—`<circle>` tags with explicit `cx`, `cy`, and `r` attributes—rather than React components. A script tag logs “React” and `index.js` imports React and ReactDOM, but no interactive behavior or data binding is present. The example demonstrates a static, hand-coded SVG composition embedded in an HTML file.
