A smiling face rendered as a static SVG graphic uses React 17 and ReactDOM to mount an app, though the visible face is drawn directly in the index.html file with hardcoded circle elements. The yellow outer circle, two black eye circles, and implied curved mouth are laid out with explicit pixel coordinates on a 960×500 canvas. The code does not implement any interaction or data-driven logic; it simply outputs a fixed, pre-defined facial composition.
