Fork of Smiley Face Part III - andré
A smiling face is drawn in yellow with a black outline, featuring two white eyes with black pupils and a curved black mouth. The illustration is rendered as an SVG using React components and D3, with the mouth created by the `d3.arc` API to define an arc path. The code sets fixed dimensions and positions for the face elements, computing the face circle and eye coordinates relative to the canvas center, and renders the result through `ReactDOM.render`.
