smiley face
A grid of randomly generated smiley faces fills the screen, each rendered as a yellow circle with black strokes, two eyes, and a curved mouth. The code creates 18 variations using React components and D3's `arc` generator for the mouth paths, with randomized dimensions for stroke width, eye position, eye radius, and mouth parameters. The SVG faces are generated in a React app from the `range` utility in D3, with each face re-rendered with different random values.
