This example draws a simple smiley face using only SVG primitives in a React-free HTML page, though the listing notes React as a possible framework for the v3 source. The face consists of three circles: a large yellow head with a black outline and two smaller black circles for eyes, all positioned within an SVG canvas. The code relies on standard SVG elements like `<circle>` and CSS styles for the page layout, with no data binding or interactivity. It demonstrates basic declarative vector graphics rendering in the browser.
