A simple SVG face, rendered with React, tracks nothing; it is a static smiling face centered in a yellow circle. The code uses the `arc` helper from `d3-shape` to define the mouth’s path, and React components construct the SVG elements, including two eyes and a stroke-bordered head. The face is positioned using a group element with a `transform` translation, and ES6 template literals set the coordinate values. The example highlights how D3’s geometry utilities can be combined with React for declarative SVG drawing.
