This example demonstrates a React and SVG-based face component, rendering a yellow circle as the head with a single eye placed relative to the screen center. The code computes the viewport dimensions and positions the SVG elements using JavaScript arithmetic on window.innerWidth and window.innerHeight. React manages the SVG elements through the `ReactDOM.render` method, while the eye's coordinates are derived from offset variables. The current output is only partially complete, showing the head and one eye, with commented-out code hinting at future additions like a mouth and second eye.
