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.

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.

This example illustrates fundamental DOM manipulation with D3.js by building a smiley face from SVG primitives. A yellow circle forms the head, with two eye circles, a mouth path created using the `arc` generator, and rectangular eyebrows. The animation uses chained `transition()` calls to animate the eyebrow group's `transform` attribute upward and then back down over two seconds each, creating a simple moving expression. The code relies on `svg.append`, `.attr`, and D3's selection and transition APIs, rendering entirely through SVG without external data.

This example demonstrates fundamental DOM manipulation with D3.js by building a yellow smiley face from SVG primitives, complete with eyes, eyebrows, and a mouth. The eyebrows animate up and down using chained `transition().duration()` calls, shifting the eyebrow group’s `transform` attribute over two seconds. The code uses `d3.select` and `d3.arc` from the D3 v7 library, setting positions via `attr` and leveraging SVG circles, rectangles, and a path for the arc-based mouth.

This example demonstrates fundamental D3.js DOM manipulation by building a yellow smiley face with animated eyebrows and eyes. The face is composed of SVG circles, rectangles, and an arc-generated mouth, all positioned using SVG attributes. D3 transitions sequentially enlarge and contract the eyes while translating the eyebrow group up and down, creating a winking expression. The code uses D3 v5 APIs including `select`, `arc`, and chained `transition` calls to animate the elements on an SVG canvas.

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.

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.

A yellow smiley face is drawn with SVG shapes: a circular head, two eyes, rectangular eyebrows, and an arc-based mouth. The code demonstrates fundamental D3.js DOM manipulation and selection, using `d3.select` to append elements and `d3.arc` for the mouth path. Animated eyebrows move up and down via chained `transition()` calls with `attr` tweening over two-second durations, showcasing D3’s built-in animation capabilities without external data.
