A simple SVG smiley face is drawn within a 960x500 viewport, centered at coordinates (480, 250). The face consists of a yellow circle with a black outline, two smaller black circles for eyes, and no mouth—the title references this as "part one." Built with React and ReactDOM, the app defines a single component that returns the SVG markup, using fixed numeric values for radii and offsets. The rendering is handled entirely through React's declarative JSX syntax, with the SVG output produced by the browser's native SVG renderer.
