Smiley Face Part II
✓ Published1🌍 Public
This example renders a full-screen smiley face using React and D3.js, with the face centered on the viewport. It shows a yellow circular head with black stroke, two dark eyes positioned symmetrically, and a smiling mouth arc composed in SVG. The mouth is drawn using `d3.arc()` with specified inner and outer radii and angular range, while all other shapes use SVG `<circle>` elements. Position and dimensions derive from `window.innerWidth` and `window.innerHeight`, with constants controlling eye offset, radius, and stroke width. React renders the SVG tree via `ReactDOM.render`.
