This example shows a simple smiley face built with React and SVG: a yellow circle for the head and two black circles for eyes. The code uses React 16.7 to render static SVG elements, with hardcoded `cx`, `cy`, and `r` attributes positioning the shapes. The rendering approach is direct SVG markup inside JSX, with no interactivity or animation. It is a partial implementation, lacking a mouth, and serves as a basic demonstration of combining React with SVG for declarative shape drawing.
