This example builds a smiling face out of basic SVG shapes using D3.js. The code creates circles for the face and eyes, rectangles for eyebrows, and an arc-generated path for the mouth, all positioned within a centered group. It uses D3’s `select`, `attr`, `append`, and `transition` with `duration` to animate the eyebrows moving up and down. The rendering relies on an SVG element defined in HTML, and the fixed dimensions (960 by 500) are read via `parseFloat(svg.attr(...))`. The face is composed entirely from hardcoded values, with no external data.

Let's make a face with D3.js

This example builds a simple cartoon face from basic SVG shapes, including circles for the head and eyes, rectangles for eyebrows, and a path for the mouth. The face is grouped and centered within the SVG canvas. The animation is driven by D3 transitions, which sequentially move the eyebrows downward over two-second intervals. The code uses D3 v5's selection, arc, and transition APIs to construct and animate the elements, with the mouth generated using the `d3.arc` geometry generator to create a curved path.

Let's make a face with D3.js!

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.

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!

A smiling face drawn with SVG shapes animates its eyebrows up and down in a looping motion. The example uses D3.js v6 to construct the face from circles, rectangles, and an arc-generated mouth, centered within an SVG canvas. D3 transitions drive the eyebrow animation by repeatedly updating the transform attribute of the eyebrow group. The code imports `select` and `arc` from D3, with hardcoded dimensions for the facial features.

Let's make a face with D3.js!

This example demonstrates fundamental DOM manipulation with D3.js by constructing a smiling face and animating its eyebrows. The code appends SVG shapes—circles for the face and eyes, rectangles for the eyebrows, and a path for the mouth—using D3’s `select` and `append` methods. The eyebrows move via chained `transition()` calls with a two-second duration, shifting their vertical position and then returning. The scene is rendered in an SVG canvas with a 960 by 500 coordinate space, centered through a transform.

Let's make a face with D3.js!

This example uses D3.js to build a smiley face whose eyebrows animate. The code selects an SVG element, sizes it to the full browser window, and appends a rounded rectangle as the background. It demonstrates fundamental DOM manipulation by chaining D3 methods like `select` and `append` to create the face’s parts, with the eyebrow movement driven by simple data-driven updates in the same SVG structure. The project relies on D3 v5 and renders entirely as SVG.

Let's make a face with D3.js!

A smiling face rendered with SVG shapes animates its eyebrows in a looping bounce. The example uses D3.js v5 selections and transitions to build the face from circles, rectangles, and an arc path for the mouth. The `arc` generator creates the smile, while chained `transition` calls with specified durations move the eyebrow group and apply rotations. The React framework wraps the D3 code, which targets an SVG element sized 960 by 500.

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.
