Let's make a face with D3.js!

A smiling face is drawn with SVG shapes, and its eyebrows animate upward and downward in a loop. The face is constructed using D3.js v5’s `select` and `append` to create circles for eyes, rectangles for eyebrows, and a `path` for the mouth via the `arc` shape generator. The eyebrows’ movement is driven by chained `transition().duration()` calls that alter the group’s `transform` attribute. The code relies on D3’s DOM manipulation and transition APIs, with all rendering occurring in an SVG viewport.

A smiling face is drawn with SVG shapes, with its eyebrows animating up and down in a repeating loop. The example demonstrates fundamental DOM manipulation in D3.js v5, using `select` and `append` to build circles, rectangles, and a path. The mouth is created with the `d3.arc` API, and the eyebrow motion relies on chained `transition().duration()` calls to alternate the transform attribute, creating a simple, continuous facial animation.

This example creates a smiling face from basic SVG shapes, with its eyebrows repeatedly moving up and down. It demonstrates fundamental D3.js DOM manipulation by appending and styling circles, rectangles, and a path for the mouth. The code uses `d3.select`, `d3.arc` for the mouth, and chained `transition().duration()` calls to animate the eyebrow group’s transform attribute. The face is centered via a translated `<g>` element, with eye spacing and offsets defined as numeric constants.

A smiling face rendered in SVG is drawn with D3.js, using geometric shapes for the head, eyes, eyebrows, and a mouth created with the `d3.arc` path generator. The example demonstrates a looping animation where the eyebrows repeatedly move downward and back upward via chained `transition.attrTween` calls, while the static face elements remain fixed. The code relies on D3 selections and attribute manipulation, with the SVG canvas set to 960 by 500 pixels and centered via a transformed group.

A smiley face rendered with D3.js demonstrates basic DOM manipulation and animation. The code uses D3 selections to append SVG circles for the face and eyes, rectangles for eyebrows, and an arc-generated path for the mouth. A two-stage `transition` moves the eyebrow group vertically over four seconds, creating an animated expression. The face is centered via SVG transforms, with all shapes drawn using D3's `select`, `append`, `attr`, and `transition` APIs.

This example demonstrates fundamental DOM manipulation with D3.js by constructing an animated smiley face in an SVG. The code uses `d3.select` to append circles for the eyes, rectangles for the eyebrows, and an `arc()` generator for the mouth. A chained `transition()` with a 2000-millisecond duration moves the eyebrows up and down repeatedly, showcasing simple animation. The face is centered with a `g` element, and all shapes are drawn using D3’s SVG helper methods.

A smiling face rendered in SVG animates its eyebrows, pupils, and cheeks. The code constructs the face using D3.js v5, creating circles for the head, eyes, pupils, cheeks, and an arc path for the mouth. Animation is achieved through chained `transition().duration()` calls on the SVG groups, moving the eyebrows and pupils in a repeating pattern. The example demonstrates fundamental DOM manipulation with D3's `select` and `append` methods, alongside the `arc` generator for the mouth and eyebrow shapes.

Let's make a face with D3.js!

This example builds a smiling face out of basic SVG shapes, with animated eyebrows that move up and down. Using D3.js v5, the code selects the SVG element, appends and positions circles for the eyes, rectangles for the brows, and an arc-generated path for the mouth. A transition chain on the eyebrows group animates the transform attribute over two two-second intervals, creating a subtle, looping expression change.
