This gallery example draws a stylized smiley face using SVG elements. The face is assembled from basic shapes, including a large circular head, two eyes with green pupils, and a small purple nose, all rendered with distinct stroke and fill colors. The mouth is created as an arc using `d3.arc()`, while the eyebrows and hair are composed of multiple line elements. The visualization is constructed with React, using both ReactDOM and the D3.js library to calculate the mouth's path, and renders entirely through SVG.
