Fork of Smiley Face Part II
This example shows a classic smiley face rendered across the full browser window, with a yellow circular head, black outline, and two dark eyes. The face is centered dynamically, and the head's radius and eye positions are calculated from the window’s dimensions. The visualization is built using React to construct the SVG elements, with D3.js available for potential data manipulation, though only static SVG shapes are drawn here. The code defines constants for the face's geometry and uses a transformed group to center all elements.
