This example displays a simple yellow smiley face drawn as a circle with two smaller black circles for eyes on a 960-by-500 SVG canvas. Rendered using React and ReactDOM within a single component, the visualization demonstrates the SVG `circle` element with props such as `cx`, `cy`, `r`, `fill`, and `stroke` for styling. The code draws only the face’s outline and eyes, leaving the mouth unfinished, as the README notes. The source uses static hardcoded coordinates rather than any data processing or animation library.
