Fork of Smiley Face Part II
This example renders a yellow smiley face on a full-screen SVG canvas using React and ReactDOM. It computes the window dimensions to center the face, drawing a large yellow circle with a black stroke as the head, two small black eyes positioned symmetrically, and no mouth. The code relies on React’s JSX syntax and SVG elements like `<circle>` and `<g>` with transforms, using absolute pixel values derived from the viewport size.
