Fork of Smiley Face Part II
This example shows a large yellow smiley face rendered with React and D3, filling the entire browser window. The face features white eyes with blue pupils, a black stroke arc for the mouth, and a row of white teeth rectangles at the bottom. Using React for component structure and D3’s `arc` generator for the mouth path, the visualization scales its dimensions to the viewport, drawing static SVG elements with fixed offsets and radii.
