This example draws a simple yellow smiley face using React and D3 within an SVG canvas. The face consists of three circles: a large yellow circle for the head, and two smaller black circles for the eyes, all positioned using explicit coordinates. The code imports the `arc` function from D3 but does not use it, instead relying on React to render the SVG elements. The visualization is static, with a black stroke border around the head, and is built using React's `ReactDom.render` method.
