Let's make a face with D3.js!

A yellow smiley face rendered in SVG has animated eyebrows that rise and fall. The face is built through basic DOM manipulation with D3.js, appending circles, rectangles, and an arc-shaped mouth to an SVG group. A chained `transition` with a 2000-millisecond duration moves the eyebrow group up and down. The example demonstrates core D3 v5 selections and transitions for simple, focused visual animations.

Let's make a face with D3.js!

A yellow smiley face is drawn in SVG, and its eyebrows animate upward and downward in a looping motion. The face is built entirely through D3.js v5 selections, appending circles for the eyes and a path created with the `arc` generator for the mouth. Eyebrow movement is driven by chained `transition().duration()` calls that alternate the eyebrow group’s vertical translation. The code imports `select` and `arc` from D3 and positions all elements relative to the SVG’s center.

Let's make a face with D3.js!

A yellow smiley face with animated eyebrows demonstrates D3.js DOM manipulation and SVG rendering. The code uses `d3.select` and `d3.append` to construct circles, rectangles, and a mouth path via `d3.arc`. Chained `transition().duration()` calls repeatedly shift the eyebrow group’s `transform` attribute, creating a bouncing motion. All elements are centered within a fixed 960×500 SVG viewport.

Let's make a face with D3.js!

A yellow smiley face is drawn in SVG, with two circular eyes, a mouth shaped by a D3 arc path, and rectangular eyebrows that animate by moving upward and back down. The code uses D3.js v5’s `select`, `arc`, and `transition` APIs to construct and manipulate the SVG elements, applying transforms to position face features and trigger the eyebrow movement over timed transitions.
