This example displays a simple smiley face drawn with vector shapes in an SVG canvas. The face consists of a large yellow circle with a black outline, plus two smaller black circles for eyes, all rendered directly in the markup. The visualization relies on React 18.2.0’s production UMD build, though no React components are actually used; instead, the SVG elements are declared statically in the HTML body. The code sets the page margin to zero and hides overflow, ensuring the 960 by 500 pixel graphic fills the viewport without scrollbars.
