Parte 1 Carita Feliz
This example shows a smiling face constructed from simple geometric shapes, centered within a 960 by 500 pixel SVG canvas. The face is drawn using D3's `arc` generator to create a semi-circular mouth, while React handles the declarative rendering of the elements. A yellow circle forms the head, with black stroke outlines, and two smaller black circles serve as eyes. All shapes are positioned relative to the canvas center using SVG transforms.
