Fork of Hello HTML
A grid of sixteen yellow smiley faces is rendered with React and SVG. Each face is randomly generated, with variations in stroke width and eye radius, while the mouth and nose are drawn as arcs using D3’s `arc` function. The faces are created by composing reusable components—`Face`, `Eye`, `Mouth`, and `Nose`—that are instantiated within a React app and rendered into an SVG container.
