Let's make a face with D3.js!

This example demonstrates how to build a simple animated smiley face using D3.js. It shows a yellow circle with eyes, eyebrows, and a mouth, all constructed through fundamental DOM manipulation. The code uses `d3.select` to target the SVG element, `d3.append` to create shapes, and a chained `d3.transition` sequence to animate the eyebrows moving up and down over two-second intervals. The mouth is drawn as an arc using `d3.arc` with specified inner and outer radii. The rendering is SVG-based, with all elements positioned relative to the center of the canvas.

A D3.js example builds a yellow smiley face with eyes, eyebrows, and an arc-based mouth, then animates the eyebrows upward and back down using chained `transition` calls on SVG `rect` elements. The face is centered via a `g` transform, with `d3.arc` generating the mouth path. The code selects an SVG, appends shapes with explicit pixel offsets, and relies on D3 v5’s `select`, `attr`, and `transition` APIs to demonstrate fundamental DOM manipulation and animation.

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 shows a yellow smiley face built with SVG shapes whose eyebrows animate upward and downward in a looping motion. The code demonstrates fundamental D3.js DOM manipulation by selecting the SVG canvas, appending groups for positioning, and constructing circles, rectangles, and an arc-based mouth using `d3.select`, `d3.arc`, and chained `transition().duration()` calls. The face is centered via a translated group, with all coordinates calculated relative to the viewport dimensions.

This example demonstrates fundamental DOM manipulation with D3.js by constructing an animated smiley face from basic SVG shapes. The face comprises a yellow circle, two eyes, and a mouth drawn as an arc path, with eyebrows that move up and down using chained `transition().duration()` calls. The code builds the face by appending circles, rectangles, and a path to the SVG, using `d3.select` and `d3.arc` from D3 v5.

A smiley face rendered in SVG uses D3.js to demonstrate fundamental DOM manipulation and animation. The code builds the face from primitive shapes—a yellow circle for the head, black circles for the eyes, a path for the mouth—and positions them via group transforms. Two animated eyebrows, implemented as rectangles, shift vertically using chained `transition() .duration(2000)` calls. The example reads SVG dimensions with `parseFloat`, uses helper methods like `select`, `append`, and `attr`, and draws the mouth with the `arc()` shape generator from D3's shape module.

A smiley face built with SVG shapes demonstrates D3.js v5 DOM manipulation and chained transitions. The code uses `d3.select`, `append`, and `attr` to construct a yellow circle with eyes, rectangular eyebrows, and an arc-based mouth via `d3.arc()`. A two-step `transition().duration(2000)` sequence moves the eyebrow group up and down, creating an animated expression. The example relies on D3’s data-join-free imperative style, directly targeting SVG elements within a 1000×500 viewport without external data.

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.
