This example shows a simple yellow smiley face rendered with SVG, consisting of a large outlined circle for the head and two smaller circles for the eyes. Built with React and ReactDOM, the visualization defines all geometric values—such as center coordinates, radii, and stroke width—as JavaScript constants, then uses those to position the SVG circle elements. The face’s dimensions are fixed at 960 by 500 pixels, with the head centered at the midpoint and the eyes offset slightly from the center.
