Smiley Face
A simple SVG smiley face is drawn using two overlapping circles, a large yellow circle for the head and a smaller black circle for one eye. The React application renders the graphic through the `ReactDOM.render` method, creating an SVG element with hardcoded circle positions and dimensions. The code uses React's JSX syntax to define the SVG markup directly, with the `cx`, `cy`, and `r` attributes controlling circle placement and size. Only one eye is visible in the rendered output, despite the HTML comment referencing both eyes.
