A D3.js smiley face animates by moving its eyebrows up and down in a looping transition. The face is built entirely with SVG primitives—circles for the eyes, rectangles for the eyebrows, and an arc-generated path for the mouth—positioned within a centered group. Using `d3.select`, `d3.arc`, and chained `transition().duration()` calls, the code shifts the eyebrow group’s vertical translation between two offsets. A black background and yellow face with black strokes create clear visual contrast. The example demonstrates fundamental DOM manipulation and SVG rendering with D3 v5.

This example demonstrates fundamental D3.js DOM manipulation by animating a yellow smiley face whose eyebrows move up and down in a continuous loop. The face is drawn using SVG shapes—circles for the eyes and head, rectangles for the eyebrows, and a path generated with d3.arc() for the mouth. The animation is driven by chained transition() calls that alternately shift the eyebrow group’s transform attribute over two-second intervals. The code imports select and arc from D3 v5 and appends elements to a fixed 960×500 SVG canvas.

A yellow smiley face is drawn in SVG, centered within a 960-by-450 canvas, with eyes, a mouth, and eyebrows that animate upward and back down over two seconds. The example demonstrates fundamental DOM manipulation using D3.js v5, building the face with `d3.select`, `append`, and the `d3.arc` shape generator for the mouth. The eyebrows’ movement is driven by chained `transition().duration(2000)` calls that change the group’s `transform` attribute. All shapes are plain SVG elements, and the animation relies entirely on D3’s transition system.

A yellow smiley face with animated eyebrows demonstrates basic DOM manipulation in D3.js v5. The face is built using SVG shapes—circles for the head and eyes, rectangles for eyebrows, and an arc-generated path for the mouth. Eyebrows move up and down repeatedly via chained `transition()` calls with 2000-millisecond durations. The code imports `select` and `arc` directly from the d3 module, and centers all elements using SVG group transforms.

A yellow smiley face built with SVG and animated with D3 v5 demonstrates fundamental DOM manipulation. The code uses `d3.select`, `append`, and `attr` to construct circles for the face and eyes, rectangles for the eyebrows, and a `d3.arc` path for the mouth. A chained `transition().duration(2000)` moves the eyebrow group up and down in a looping motion, while the iris and additional features remain static. The example relies on SVG attributes and D3’s enter/update/exit-free imperative style, with no external data source.

A yellow smiley face is drawn in SVG, with circular eyes and rectangular eyebrows that animate vertically. The eyebrows move up and down in a repeating loop using D3’s `transition()` method, while the mouth is created with the `d3.arc` shape generator. The code selects SVG elements with `d3.select`, uses `d3.arc` for the path, and animates attributes via chained transitions. Drawing is done over two seconds per movement, with the face centered in a 960×500 viewport.

A smiley face drawn with D3.js animates its eyebrows in a continuous up-and-down motion, using a yellow circle for the face, two circles for eyes, and an arc for the mouth. The code selects the SVG element, appends groups and shapes with `select` and `append`, and drives the eyebrow movement with chained `transition` calls that alternate between two vertical positions over two-second durations. The face is centered via a transform, and all dimensions are computed from the SVG's width and height attributes.

This example shows a yellow smiley face with animated eyebrows, which shift upward and then return to their resting position in a looping motion. The face is constructed entirely from SVG primitives—circles for the eyes and head, rectangles for the brows, and a path for the mouth—all centered within a 960×500 viewport. Using D3 v5, the code demonstrates DOM manipulation through chained `select`, `append`, and `attr` calls, while the eyebrow animation relies on the `transition` API to tween the `transform` attribute over 1500 milliseconds.
