Smiley Face Part I
A grid of eighteen small SVG smiley faces, each generated with React and D3, fills the canvas. The faces use a yellow circle with a black stroke for the head, two circles for the eyes, and a D3 arc path for the mouth, with random values for eye radius, mouth radius, and mouth width creating variation. The positioning is set by translating a container group, and the D3 `range` function produces the face count.
