Smiley Face Part I
This visualization shows a yellow smiley face centered on an SVG canvas. The face consists of a large yellow circle with a black outline, two black circular eyes positioned symmetrically, and a curved mouth created using a D3 arc path. The code uses React to render the SVG elements, with D3’s `d3.arc` API generating the mouth’s path coordinates. The face is drawn deterministically without external data, using fixed pixel dimensions and offsets.
