Face
A smiling face is drawn inside an SVG canvas through D3.js v5. The visualization uses a static, stylized face composed of simple geometric shapes—eyes, nose, and a curved mouth—positioned within a 960×500 viewport. The rendering relies on D3’s selection and attribute-setting methods to generate the SVG elements directly, with styling controlled by an external CSS file. No data source appears; the face is a purely decorative vector graphic, with the blank `<svg>` element populated programmatically via D3.
