This example shows a single large yellow circle with two smaller black circles positioned to resemble a face, rendered directly in SVG via static markup in the HTML. The code uses React 18 to mount an `App` component, though the visual itself is defined outside React in the `index.html` file, with the circles' coordinates and stroke properties set manually. The page loads React and ReactDOM from unpkg, and the SVG has a fixed width of 960 and height of 500, with no D3.js API calls present despite the title referencing D3.
