This example demonstrates fundamental D3.js DOM manipulation by constructing an animated smiley face from SVG shapes. The face consists of a yellow circle head, two dark eyes, rectangular eyebrows, and an arc-based mouth, all positioned relative to an SVG group centered on the canvas. Using d3 selection and transition methods, the eyebrows perform a repeated up-and-down motion over two-second intervals. The code relies on d3.select, d3.arc for the mouth path, and chained transition.attrTween (via transition.attr) to animate the eyebrow group’s vertical offset, showcasing basic data-driven document updates without any external dataset.

Let's make a face with D3.js!

This example demonstrates fundamental DOM manipulation with D3.js by building an animated smiley face from SVG shapes. A yellow circle forms the head, with eyes, eyebrows, and a mouth added as separate elements. The code uses d3.select and append to construct the face, then applies chained transitions to move the eyebrows up and down repeatedly. The mouth is drawn using d3.arc with specified inner and outer radii and angles. All shapes are positioned relative to a centered group, with animation running for two seconds per eyebrow movement cycle.

Let's make a face with D3.js!

This example demonstrates fundamental DOM manipulation and animation with D3.js by constructing a smiley face from SVG shapes and animating its eyebrows. A yellow circle forms the head, with eyes, rectangular eyebrows, and an arc-based mouth positioned using D3 selections and attribute setters. The code uses d3.select, d3.arc, and chained transitions with .transition().duration() to move the eyebrow group up and down over two 2-second cycles. All elements are appended to an SVG container, with positioning handled via transform attributes.

Let's make a face with D3.js!

This example demonstrates fundamental D3.js DOM manipulation by building a smiley face from SVG elements, with animated eyebrows that move up and down. The code uses D3 selections to append a yellow circle for the head, circles for the eyes, rectangles for the eyebrows, and an arc-generated path for the mouth. It applies `transition` with a two-second duration to animate the eyebrow group’s vertical position, showcasing data-driven document updates. The rendering uses SVG within a 960x500 viewport, driven entirely by D3’s `select` and `arc` APIs.

Let's make a face with D3.js!

This example demonstrates fundamental DOM manipulation with D3.js by constructing a smiley face from basic SVG shapes, including a yellow circle head, eyes, eyebrows, and an arc-based mouth. The code explicitly appends each shape using `d3.select` and `.append`, positioning them with translation attributes. The prominent behavior is an animated eyebrow movement, achieved through a chained `transition().duration(2000)` on the eyebrow group, which moves the brows down and back up. The rendering is SVG, and the animation is visible in a video embed, with the entire face recreated using only D3’s core selection and attribute methods.

Let's make a face with D3.js!

This example demonstrates fundamental DOM manipulation with D3.js by building an animated smiley face. The visualization shows a yellow circle with eyes, eyebrows, and a mouth, where the eyebrows perform a continuous up-and-down movement. The code uses D3’s `select` and `append` to construct SVG elements, and `transition().duration()` to animate the eyebrow group’s `transform` attribute over 2000-millisecond intervals. The mouth is drawn with a `d3.arc` path generator, while hardcoded constants control facial feature positioning and spacing. The rendering is entirely SVG-based, with static input values defining the geometry.

Let's make a face with D3.js!

A yellow smiley face with movable eyebrows demonstrates fundamental DOM manipulation with D3.js. The code selects an SVG element and builds the face from primitives: circles for the head and eyes, rectangles for the eyebrows, and an arc-generated path for the mouth. Using D3's selection and transition methods, the eyebrows animate vertically over two seconds, then return, cycling through the eyebrow group's transform attribute. The example relies on d3.select, d3.arc, and chained transitions to compose and animate SVG shapes.

Let's make a face with D3.js!

This example demonstrates how to construct a simple smiley face from SVG shapes and animate its eyebrows using D3.js. The face is built with a yellow circle, two dark eyes, and a mouth drawn as an arc path, all grouped and positioned within an SVG canvas. A D3 transition with a two-second duration repeatedly moves the eyebrows up and down between two y-offsets, creating a subtle bobbing expression. The code relies on the `select`, `append`, `attr`, and `transition` APIs to manipulate the DOM directly.

Let's make a face with D3.js!

This example demonstrates fundamental D3.js DOM manipulation by constructing a smiley face from SVG shapes, with a gentle animation of its eyebrows. The code builds a yellow circle head, eyes, and a mouth using D3’s `select`, `attr`, and an `arc` generator for the path. The eyebrow rectangles transition vertically via chained `transition().duration(2000)` calls, moving them down and back up. It uses D3 v5, rendering to a static SVG canvas with no external data, focusing purely on programmatic element creation and animation.
