Smily face
A single yellow circle with a black outline renders as a simplified smiley face on a blank canvas. The example demonstrates how to draw basic SVG shapes using React, creating a static vector graphic with a fixed 960x500 viewport. The code imports React and ReactDOM from the React 17 UMD build and uses JSX to declare a circle element with specified radius, center coordinates, fill color, and stroke properties. No interactive behavior or animation is present, as the component returns only one static SVG element.
