This example shows a static smiley face composed of three SVG circles: a large yellow face with black outlines and two smaller eyes. It serves as a simple introduction to rendering shapes with React by loading React 16.7.0 from a CDN and logging the library to the console. The SVG elements use explicit `cx`, `cy`, `r`, and `stroke-width` attributes to position the face and eyes on a 960×500 canvas, with CSS hiding overflow. The code does not include interactive behavior or dynamic data.
