Let's make a face with D3.js!

D3.js constructs an animated smiley face by manipulating SVG shapes. A yellow circle forms the head, with two static eyes and a mouth drawn using the `arc` path generator. The eyebrows, rendered as rectangles, animate upward and downward over two seconds using chained `transition().duration()` calls on the SVG group, demonstrating fundamental DOM selection and attribute mutation. The code uses the `select` API to target the root SVG element.

A smiling face built from basic SVG shapes appears on a yellow circle, with eyebrows that bob up and down through a looping transition. The example uses d3-selection and d3-shape to construct the face, positioning eyes, eyebrows, and a mouth with coordinate offsets. An arc generator creates the mouth, while chained transition calls animate the eyebrow group’s vertical position over two-second intervals, producing a playful expression. The code renders entirely in SVG within a 960 by 500 viewport.

A smiling face built from SVG shapes animates its eyebrows up and down in a looping transition. The example constructs the face from basic geometric elements—a yellow circle for the head, two small circles for eyes, rectangles for brows, and an arc path for the mouth—centered via a translated group. Using D3 v5, the code applies chained `transition()` and `.attr()` calls to move the eyebrow group repeatedly, while the `d3.arc()` helper generates the mouth’s curved outline. The rendering relies on SVG appended directly to the page’s `<svg>` element.

A D3.js animation draws a yellow smiley face with eyes, a mouth, and eyebrows that move. The SVG is centered, and the code uses D3's `select` and `append` to build shapes, `arc` for the mouth path, and `transition().duration(2000)` twice to animate the eyebrow group up and down in a repeating sequence. The face is static except for the eyebrows, which shift vertically.

A smiling face built from SVG shapes animates as its eyebrows lift and lower repeatedly. The yellow circle head, eyes, and mouth are drawn using D3 selections with attributes like radius and position, while an arc path forms the smile. The eyebrows use D3's `transition().duration()` to shift vertically in a looping sequence. All shapes are centered via a translated group, with the example rendered entirely in SVG using d3.v5.

This example uses D3.js v5 to construct a smiling face from SVG primitives, with animated eyebrows that move up and down over time. The face consists of a yellow circle, two eyes, eyebrows, and a mouth drawn using an arc path. The animation is handled through chained `transition().duration(2000)` calls that alternately shift the eyebrow group’s `transform` attribute, creating a simple looping motion. The code relies on methods like `select`, `append`, and `attr` for DOM manipulation, along with D3’s `arc` generator for the mouth shape.

This D3.js v5 example demonstrates fundamental DOM manipulation by building a smiling face from SVG primitives, including yellow circles for the head and eyes, and rectangular eyebrows that animate upward and downward. The code constructs the face using `d3.select`, `svg.append`, and shape methods like `.attr`, while `d3.arc` generates the mouth as a path with specified inner and outer radii. A chained `transition().duration(2000)` sequence repeatedly moves the eyebrows up and down, creating a simple looping animation.

A smiling face drawn with SVG shapes responds to a looping animated transition: the eyebrows move upward, hold, then return. The example demonstrates fundamental D3.js DOM manipulation, building the face from a yellow circle, two dark eyes, rectangular eyebrows, and a smile-shaped path generated with the `d3.arc()` function. D3.js v5 selects the SVG element, appends groups for coordinated positioning, and uses `transition().duration(2000)` to animate the eyebrow group's vertical offset. All elements are styled directly via attributes like `fill` and `stroke` within an 960×500 SVG canvas.
