This example shows a yellow smiley face rendered as a scalable vector graphic, with two black eyes and a circular head, all drawn using React and ReactDOM to create SVG elements. The code calculates the head radius, eye positions, and offsets based on the current browser window dimensions, centering the face dynamically. It uses React’s declarative JSX syntax to instantiate the SVG circles, relying on the react and react-dom production libraries to mount the visualization into the page’s root div. The face is static, presenting a simple geometric composition without animation or interaction.
