Fork of Smiley Face Part II
A smiley face is drawn as a full-screen SVG graphic, centered within the browser window. The face consists of a yellow circle with a black outline, two black eyes, and a mouth. The code uses React to render the SVG elements, calculating the dimensions and positions based on the window's inner width and height. The example demonstrates a responsive approach, where the face's size and component positions scale proportionally with the viewport, utilizing React's declarative component structure to build the graphic.
