Let's make a face with D3.js!

This example builds a yellow smiley face with D3.js, featuring eyes, eyebrows, and a mouth rendered as SVG shapes. The code uses D3 selections to append a circle for the face, two circles for eyes, rectangles for eyebrows, and an arc path for the mouth. A chained `transition` with a 2-second duration animates the eyebrow group’s vertical position upward and then back, creating a moving-brow effect. The face is centered within a 960×500 SVG, and the animation runs once on page load.

A D3.js animation builds a yellow smiley face centered in an SVG canvas, with eyebrows that repeatedly move upward and then return to their original position. The face is constructed from SVG circles for the eyes, rectangles for the eyebrows, and a path for the mouth generated with the `d3.arc` API. D3’s `transition` method animates the eyebrow group’s `transform` attribute over two-second intervals. The code uses D3 v5’s `select` and `append` functions to manipulate the SVG DOM directly.

A yellow smiley face is drawn with SVG shapes: a circular head, two eyes, rectangular eyebrows, and an arc-based mouth. The code demonstrates fundamental D3.js DOM manipulation and selection, using `d3.select` to append elements and `d3.arc` for the mouth path. Animated eyebrows move up and down via chained `transition()` calls with `attr` tweening over two-second durations, showcasing D3’s built-in animation capabilities without external data.

A D3.js animation builds a yellow smiley face with a black outline, two eyes, and a mouth, then animates its eyebrows upward and downward using chained `transition` calls. The SVG is constructed by selecting the root element, setting a viewBox of 960 by 500, and translating a group to the center. The code uses D3’s `select`, `arc`, and `transition` APIs to draw circles, rectangles, and a path, with the mouth as an arc.

A yellow smiley face with animated eyebrows is drawn in SVG using D3.js v5. The face is centered via a translated group, with circles for eyes, rectangles for eyebrows, and an arc-generated path for the mouth. The eyebrows transition upward and back downward over two seconds each using chained `transition` and `duration` calls, demonstrating fundamental DOM manipulation and animation with D3's `select`, `arc`, and transition API.

A yellow smiley face with animated eyebrows is rendered in SVG using D3.js. The face is constructed from basic SVG shapes: circles for the eyes, rectangles for the eyebrows, and an arc path for the mouth. The code uses D3 selections (`select`, `append`) and the `arc` generator, with `transition().duration()` to move the eyebrows up and down. The animation runs once, lifting the eyebrows 50 pixels and then returning them to their original position, demonstrating fundamental DOM manipulation with D3 v5.

A D3.js example draws a yellow smiley face with animated eyebrows that raise and lower in a continuous loop. The face is constructed using SVG primitives: circles for the head, eyes, and an arc-shaped mouth, while rectangles form the eyebrows. The animation relies on D3's `transition().duration()` method to interpolate the eyebrow group's transform attribute between two vertical positions. The code demonstrates straightforward DOM manipulation via `d3.select` and `d3.append`, with all elements positioned absolutely within a 960 by 500 pixel SVG canvas.

A yellow smiley face with moving eyebrows is assembled on an SVG canvas using D3.js v5. The code builds the face from primitive shapes—circles for the eyes, rectangles for the brows, and a path from the `d3.arc()` generator for the mouth. The eyebrows are animated via chained `transition().duration()` calls that shift their container group up and down over four seconds. All dimensions are derived from the SVG's width and height attributes, and the face is centered with a translated `<g>` element.
