An interactive SVG face built with D3.js v5 demonstrates how to construct a playful character from basic geometric shapes. The example uses `d3.select` to target the empty `svg` element within the 960×500 viewport and dynamically appends circles, ellipses, and paths for the eyes, mouth, and head. The code imports a separate local module via ES6 `import` syntax to display a text message, showing modular code organization. Rendering relies on SVG attributes and D3’s data-join methods, though the static sketch does not include animation or user interaction.
