This example uses D3.js (v5) to construct an animated smiley face entirely through SVG primitives and DOM manipulation. It shows how a face composed of a circle, eyes, eyebrows, and a mouth can be built and animated on an empty 960x500 SVG canvas. The code demonstrates chained `transition().duration()` calls to move the left eyebrow up and down over two seconds, while the right eyebrow is a rectangle and the mouth is an arc path generated with the `d3.arc` API. All elements are positioned through SVG attributes and groups, with no external data—the face is purely synthetic.

Let's make a face with D3.js!

This example shows a smiley face drawn with SVG circles, rectangles, and an arc for the mouth. Its eyebrows bounce up and down repeatedly in an animated loop. The code demonstrates fundamental DOM manipulation with D3.js v5, using `select`, `append`, and chained `transition().duration()` calls to animate the eyebrow group’s transform. The face uses hardcoded dimensions, no external data, and renders entirely through SVG primitives within a 960x500 canvas.

Let's make a face with D3.js!

This example uses D3.js v5 to demonstrate fundamental DOM manipulation by building a stylized smiley face from SVG shapes. The face features animated eyebrows that move up and down via chained `transition().duration()` calls on a group element, creating a dynamic expression. The code explicitly constructs each facial component—circle for the face, two eye circles, rectangular eyebrows, and an arc-based mouth path—using D3’s `select`, `append`, and `attr` methods within an SVG canvas. The `arc()` generator calculates the mouth’s path with specified inner and outer radii.

Let's make a face with D3.js!

This example builds a smiley face in SVG using D3.js v5, constructing the head, eyes, eyebrows, and mouth from geometric primitives like `circle`, `rect`, and `d3.arc`. The face is centered via SVG transforms, with the eyebrows animated upward and back down using chained `transition().duration(2000)` calls on a group element. No external data is loaded; the visualization focuses on programmatic DOM manipulation and declarative animation within an SVG canvas.

Let's make a face with D3.js!

This example demonstrates fundamental DOM manipulation with D3.js by constructing a smiley face from SVG shapes, including a circle head, rectangular eyes, and an arc-based mouth. The face’s eyebrows animate vertically in a looping transition, moving up and then returning to their original position over four seconds. The code uses D3 v5 selections and the `arc` helper to generate the mouth path, while `transition().duration()` drives the eyebrow movement. The entire figure is centered within a 960×500 SVG canvas, with styling applied via an external stylesheet.

Let's make a face with D3.js!

This example uses D3.js to build an animated smiley face in SVG, whose eyebrows lift and lower in a looping transition. It shows fundamental DOM manipulation by selecting an SVG element, appending grouped shapes, and binding attributes for the face’s circles, rectangles, and an arc-based mouth. The animation relies on chained `transition().duration()` calls to move the eyebrow group’s transform. Specific APIs include `select`, `append`, `attr`, and `arc` from D3 v5, with coordinates computed from hardcoded spacing and offset values.

Let's make a face with D3.js!

This example demonstrates how D3.js can animate a smiley face by manipulating SVG shapes, specifically moving its eyebrows up and down over a four-second loop. The code builds the face using `d3.select` to append SVG elements like circles, rectangles, and a path for the mouth, with an arc generator defining the mouth’s curve. The eyebrows use chained `transition().duration(2000)` calls to shift their vertical position, creating the facial animation. The entire face is centered within an SVG canvas using a `<g>` element, with hardcoded layout constants for eye spacing and dimensions.

Let's make a face with D3.js!

A smiley face rendered as an SVG animation demonstrates core D3.js DOM manipulation. The code appends geometric elements—circles for the face and eyes, rectangles for eyebrows, and a path built with `d3.arc` for the mouth—onto an SVG canvas. Chained `transition().duration()` calls animate the eyebrow group’s vertical position, moving them up and down over four seconds. Using `d3.select` to create and transform elements, this example highlights how D3 binds data-independent shapes and drives simple timeline-based motion without external data sources.
