Let's make a face with D3.js!

This example demonstrates fundamental DOM manipulation with D3.js by building a smiley face whose eyebrows animate up and down. The code uses `d3.select` to target an SVG element, `svg.append` to construct geometric shapes like rectangles and arcs, and `transition().duration()` to create a looping eyebrow movement over two seconds. The face is rendered as a static SVG with a semi-transparent green rectangle, red-stroked eyes, and a mouth drawn via the `d3.arc` shape generator, all centered using SVG group transforms.

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.

This example builds a smiling face from basic SVG shapes using D3.js, with animated eyebrows that move up and down in a looping transition. The code selects an SVG element, centers a group, and appends a circle for the head, circles for eyes, rects for eyebrows, and a path for the mouth generated with the `d3.arc()` helper. Using `d3.transition()` and `.duration(2000)`, the eyebrows shift vertically twice, creating a repetitive motion. The demonstration focuses on fundamental DOM manipulation—such as `.append()`, `.attr()`, and chained transitions—while rendering entirely in SVG with no external data.

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.

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 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.

Let's make a face with D3.js!

This example displays a smiling face with animated eyebrows built entirely through D3.js v5 DOM manipulation. The SVG face consists of circles for the eyes and head, a path for the mouth, and rectangles for the eyebrows, all positioned relative to a centered group element. Using D3's selection API (`d3.select`, `d3.append`) and the `transition` method, the eyebrows animate vertically over two seconds, moving up and then returning to their original position. The drawing relies on hardcoded numeric coordinates rather than external data.

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.
