Fork of Smiley Face Part II
This example demonstrates a classic smiley face rendered with React and D3, using SVG elements to form the face’s yellow circular head, black outline, and two eye circles. The visualization adapts dynamically to the browser’s window size, centering the face and scaling its radius based on the viewport height. React manages the component structure, while D3’s `arc` module is imported but not used in the visible code. Instead, the face is drawn with plain SVG `circle` elements, with positions and dimensions calculated from fixed offsets for the eyes and center coordinates.
