Fork of Let's make a face with D3.js!
A yellow smiley face is drawn on an SVG canvas using D3.js v5, with black-outlined features and proportional spacing. The example demonstrates fundamental DOM manipulation and chained transitions, as the eyebrows move up and down in a repeating animation cycle. The code uses D3's `select`, `arc`, and `.transition()` methods to construct and animate the face, with static circles, rectangles, and a mouth path.
