Smiley Face Part I
This example shows a static smiley face rendered as a simple SVG graphic. The face consists of three circles: a large yellow circle for the head and two smaller black circles for the eyes, all drawn directly in the HTML markup. The code uses React 16.9.0 and ReactDOM to mount a separate “Hello JSX” component, though the smiley face itself is plain SVG without React involvement. The rendering approach relies on explicit SVG attributes for positioning and styling, with a viewport of 960 by 500 pixels.
