This example shows a static smiley face drawn as a single SVG circle, centered within a 960×500 viewport. It demonstrates fundamental DOM manipulation with D3.js v5, loading the library from a CDN while also including React 16.7. The code defines circle coordinates and radius as constants, then renders the element via React’s `createElement` structure. Although the project title mentions moving eyebrows, the provided code only renders the basic face without animation or additional facial features. The SVG output is styled with a full-bleed body and hidden overflow.
