smiley face
This example shows a classic smiley face rendered as a static SVG graphic: a yellow circle with a black outline, two black eye circles, and an implied mouth. The visualization is built using plain HTML5 SVG elements, with the face centered on a 960×500 canvas and positioned using explicit coordinates for each shape. The page loads the React and ReactDOM production libraries via CDN, though the actual visible graphic does not depend on React scripting; instead, the SVG markup is written directly in the HTML body. A minimal React app in `index.js` renders only a heading, leaving the smiley face as a purely declarative SVG illustration.
