Smiley Face Part 1
This example shows a static smiley face composed of three SVG circles: two black eyes and one yellow face outlined in black. The visualization is rendered using React, with direct SVG markup inside an HTML document. The circles are positioned using fixed coordinates (`cx`, `cy`, `r`) within a 960×500 viewport, and the styling uses standard SVG presentation attributes like `fill`, `stroke`, and `stroke-width`. The code loads React from a UMD build and includes a minimal JavaScript file that only imports the library, demonstrating a simple, non-interactive SVG rendering case.
