This example demonstrates how to build a static smiley face using D3.js v3, combining basic SVG shapes to construct the head, eyes, ears, mustache, and mouth. It shows fundamental DOM manipulation by appending and styling SVG elements like circles, ellipses, lines, and polygons through D3’s selection methods. The code explicitly uses `d3.select`, `d3.append`, and `d3.arc` from the `d3` and `d3-shape` libraries, with the face centered in an SVG canvas via a translation transform. The rendering approach is purely SVG-based, with all geometry defined manually in the JavaScript source rather than loaded from external data.

This interactive D3.js example builds a stylized smiley face entirely from SVG shapes, including circular eyes, a path-based mouth, and rectangular teeth. An animated sequence moves the eyebrows up and down by chaining two `transition().duration(2000)` calls, demonstrating how to create simple motion via DOM attribute transforms. The code uses `d3.select` and `d3.arc` from the D3 v5 API to construct the face's components, with all geometry centered through a single transformed group. The result shows how D3's declarative SVG manipulation can produce playful, character-driven visualizations.

This example builds a smiley face in SVG using D3.js v5, demonstrating fundamental DOM manipulation. It uses `d3.select` to append SVG elements and `d3.arc` to generate the mouth path, while circles and rectangles form the eyes and eyebrows. The face is centered on a 960×500 canvas via a transformed `<g>` group, with static features positioned by absolute coordinates. The code shows how D3 creates and styles shapes directly, though the eyebrows remain fixed rather than animating.

This example builds a smiley face with D3.js v5, animating its eyebrows in a repeating up-and-down motion. The face is constructed entirely from SVG primitives—circles for the eyes, rectangles for the eyebrows, and a path generated with the `d3.arc()` API for the mouth—all grouped and positioned via `transform` attributes. The animation uses chained `transition().duration()` calls on the eyebrow group, while static styling is applied directly to attributes like `fill` and `stroke`. The code imports `select` and `arc` from D3 and renders to a fixed 960×500 SVG canvas.

This example demonstrates how to build a smiley face using D3.js, with the ability to animate its eyebrows. It uses basic SVG elements—circles for the face and eyes, and a path generated by the `d3.arc` function for the mouth. The code sets up an SVG canvas and positions elements using translation and coordinate attributes. It relies on D3 v5’s selection and arc APIs to create the static face, which serves as a foundation for adding interactive or animated features.

This example shows a stylized smiley face built with D3.js v5, rendered as SVG with animated eyebrows that move up and down repeatedly. It demonstrates fundamental DOM manipulation by selecting an SVG element and appending groups, circles, rectangles, and a path for the mouth. The code uses D3’s `select` and `arc` APIs, along with chained `transition().duration()` calls to animate the eyebrow positions. The face is centered with a magenta circle background, and the animation loops via transition chaining without external data, relying purely on hardcoded geometric constants.

A smiley face drawn with D3.js animates its eyebrows in a repeated rise-and-fall motion. The example demonstrates fundamental DOM manipulation by building the face from SVG elements—circles for the eyes, rectangles for the eyebrows, and a path generated with the `d3.arc` helper for the mouth. Eyebrow movement uses chained `transition().duration()` calls to shift the group’s `transform` attribute, alternating between raised and lowered positions. The code imports `select` and `arc` from D3 v5 and renders entirely in SVG on a 960×500 canvas.

This fork of “Let's make a face with D3.js!” demonstrates fundamental DOM manipulation by rendering a smiley face with animated eyebrows. Using D3 v5, it selects an SVG element and applies data joins to create circles and paths, with eyebrow positions driven by `d3.interval` to simulate movement. The face itself is drawn via SVG shapes, while the script uses `d3.select` and `.attr` methods to update coordinates. The result is a lightweight, code-driven illustration of how D3 binds data to visual elements and responds to timed updates.
