This example demonstrates how to construct an animated face using SVG elements and D3.js v5. The visualization builds a face from basic geometric shapes, applying custom styling through CSS classes that define stroke colors and line properties. The code initializes an SVG canvas with fixed dimensions and relies on D3’s selection and data-binding methods to render the face components. The design emphasizes round line joins and caps for a smooth, illustrated appearance, with a compact layout that avoids page scrolling.
