Let's make a face with D3.js!

This example demonstrates fundamental DOM manipulation with D3.js by building an animated smiley face out of SVG shapes. The code uses `d3.select` to append a circle for the head, two circles for eyes, rectangles for eyebrows, and an `d3.arc()` path for the mouth. D3 transitions animate the eyebrows upward and back over four seconds. The example uses D3 v5 and relies on simple attribute setters like `.attr()` to position each element.

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.

An animated smiley face demonstrates fundamental DOM manipulation and transitions with D3.js v5. The face consists of SVG shapes, including a circle, eyes, rectangular eyebrows, and a path-based mouth. The eyebrows move up and down using chained `transition().duration()` calls. The code imports `select` and `arc` from D3, uses the `svg` selection to set up the coordinate system, and generates the mouth path with the `arc` API.

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.

This example demonstrates basic D3.js DOM manipulation by building a smiley face with animated eyebrows. The SVG circle face, eyes, and rectangular eyebrows are appended to a centered group element, while the mouth is drawn using the `d3.arc` path generator. Eyebrow movement is achieved through chained `transition` and `.attr` calls that shift the group’s transform over two-second intervals. The code relies on D3 v5 selections and transitions, rendering entirely as animated SVG without external data sources.

This example demonstrates basic DOM manipulation with D3.js by building an animated smiley face from SVG shapes. It shows how to append and style circles for the face and eyes, rectangles for eyebrows, and a path generated with the `arc` function for the mouth. The eyebrows use chained `transition` calls to move up and down over two-second intervals, while the face is centered using a `g` element with a `translate` transform. The code imports `select` and `arc` from D3 and renders entirely in SVG.

Let's make a face with D3.js!

This example uses D3.js to build a simple smiley face out of SVG shapes, with animated eyebrows that move up and down. It demonstrates fundamental DOM manipulation through method chaining: appending circles and rectangles to construct the face, and using `transition().duration()` to move the eyebrow group. The code imports `select` and `arc` from D3 v5, and draws the mouth with the `arc()` path generator. A yellow circle with a black stroke forms the head, with eyes and eyebrows positioned via SVG transforms.

Let's make a face with D3.js!

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.
