This example shows a yellow smiley face composed of SVG shapes, including a circular head, two eyes, two angled eyebrows, and an arc-based mouth, all centered within a fixed viewport. The visualization is built with React, using both `react-dom` and `d3`’s `arc` function to generate the mouth’s path geometry. Rendering occurs entirely as SVG elements, with coordinates and dimensions defined as constants within the JavaScript code, and the face is drawn using straightforward geometric primitives rather than external data.
