An interactive SVG face built with D3.js v5 is drawn using simple shapes, with JavaScript objects and arrays managing the facial features. The tutorial demonstrates modular code organization, separating the drawing logic into an index.js file while styling lines and highlighting states via CSS. It uses D3 selections and SVG path elements to construct the face. The example, sourced from a video walkthrough, serves as a beginner-friendly introduction to composing visualizations with D3’s declarative data-binding approach.
