This example shows a simple yellow smiley face rendered as an SVG, with a large circular head, two small eyes, and a black outline. The face is drawn using basic SVG circle elements positioned relative to the center of a 960 by 500 viewport. The code uses React and ReactDOM to render the SVG structure, with hardcoded values for the head radius, eye offset, and stroke width. The visualization demonstrates how React can generate declarative SVG markup for straightforward geometric shapes.
