A static smiley face rendered in SVG, comprising a yellow circular head with a black outline and two solid black eyes. The example demonstrates the basic setup of a React visualization, importing React and ReactDOM via CDN links and embedding the SVG directly in the HTML body. It uses React 16.12.0 and ReactDOM 16.12.0, with the SVG coordinates manually specified (center at 480,250, radius 245, and eyes at fixed positions). The code does not include interactive behavior or dynamic updates, serving instead as a minimal starter for facial feature composition.
