This example shows a yellow smiley face built from SVG circles, with a large head and two smaller eyes placed symmetrically around the center. React renders the SVG elements, while the dimensions and positions are computed from variables derived from a 960 by 500 viewport. The code uses ReactDOM to mount the component and assigns fixed values for the head radius, eye offsets, and stroke width. The face is incomplete, lacking a mouth, as described in the README.
