This example shows a yellow smiley face rendered as a circle with two eyes, positioned using fixed numeric coordinates for the SVG canvas. It uses React and ReactDOM to define and mount an `App` component that outputs SVG elements, with circles for the face and eyes. The code computes positions from width and height constants, and relies on React’s `createElement` via JSX to build the markup. The rendering approach is straightforward declarative SVG, with no interactive or animated behavior beyond the static composition.
