A yellow smiley face rendered in SVG uses D3.js v5 to demonstrate basic DOM manipulation and animation. The face is built by appending circles for the head and eyes, rectangles for eyebrows, and a path generated with the `d3.arc()` API for the mouth. The eyebrows animate upward and back down over two sequential 2000-millisecond transitions, showing how `selection.transition()` chains. The code uses `d3.select` to manipulate the SVG elements and sets coordinates with fixed pixel offsets for facial features.

Let's make a face with D3.js!

A yellow smiley face rendered in SVG demonstrates fundamental D3.js DOM manipulation. The face uses D3 v5's `select` and `arc` to append a circle, eyes, and a mouth, with the mouth created via the `arc()` generator. Eyebrows, drawn as rectangles, animate upward and downward through chained `transition().duration()` calls, while the mouth also shifts position over two seconds. All elements are positioned within a centered `<g>` group, showing basic SVG construction and data-driven updates.

Let's make a face with D3.js!

A yellow smiley face is drawn on an SVG canvas using D3.js v5, with its eyebrows and mouth animating through a series of transitions. The code builds the face by appending circles for the eyes and a path for the mouth, generated with the `d3.arc` helper, while rectangles form the eyebrows. A `transition` on the eyebrow group moves them up and down over two seconds, and the mouth path rotates 180 degrees. This demonstrates fundamental DOM manipulation, attribute updates, and chained transitions with D3 selections.

Let's make a face with D3.js!

A yellow smiley face rendered in SVG is centered on a 960x500 canvas, with facial features constructed from D3.js geometric primitives: circles for the eyes, rectangles for the eyebrows, and a path using the `d3.arc` builder for the mouth. The eyebrows initiate a two-stage `transition` lasting 2000 milliseconds each, moving them upward and then back to their original position. The code employs `select` from D3 v5 and relies on attribute manipulation to position elements via `translate` transforms, demonstrating fundamental DOM creation and animation without external data.

Let's make a face with D3.js!

A yellow smiley face is drawn in SVG with D3.js, using circles for the eyes and an arc-generated path for the mouth. The eyebrows are rectangles that animate upward and back down via chained `transition().duration()` calls. The example demonstrates fundamental DOM manipulation with `d3.select`, `d3.arc`, and SVG attribute binding, with all geometry positioned relative to the viewport center.

Let's make a face with D3.js!

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.

Let's make a face with D3.js!

A yellow smiley face is drawn in SVG with D3.js, featuring circular eyes, a mouth created using the `d3.arc` shape generator, and animated rectangular eyebrows. The eyebrows transition vertically over two seconds up and then back down using D3’s `.transition().duration()`. The code demonstrates basic DOM manipulation by selecting the SVG element, appending groups and shapes, and setting attributes like radius, position, and fill. All rendering is SVG-based, with no external data source.

Let's make a face with D3.js!

A yellow smiley face rendered as an SVG in D3.js demonstrates basic DOM manipulation and animation. The face is composed of simple shapes—a circle for the head, two circles for eyes, rectangles for eyebrows, and a path generated with the `d3.arc` function for the mouth. The code uses `d3.select` and `d3.append` to build the hierarchy, with a `transition` animating the eyebrows upward and back over two timed intervals. The example shows how D3 can drive SVG element attributes and transformations.

Let's make a face with D3.js!

A yellow smiley face appears in an SVG, built entirely through D3.js v5 selections and DOM manipulation. The face includes a head, two eyes, and a mouth drawn with the `d3.arc()` path generator. The eyebrows, rendered as rectangles, animate continuously via chained `transition` calls, moving up and then back over 2-second intervals. The example demonstrates fundamental SVG element creation, coordinate transforms, and data-driven attribute updates using D3's `select`, `append`, and `attr` methods.
