This example uses D3.js to build an animated smiley face in SVG, whose eyebrows lift and lower in a looping transition. It shows fundamental DOM manipulation by selecting an SVG element, appending grouped shapes, and binding attributes for the face’s circles, rectangles, and an arc-based mouth. The animation relies on chained `transition().duration()` calls to move the eyebrow group’s transform. Specific APIs include `select`, `append`, `attr`, and `arc` from D3 v5, with coordinates computed from hardcoded spacing and offset values.

Let's make a face with D3.js!

This example demonstrates how to build an animated smiley face using D3.js, with eyebrows that move up and down over time. It shows fundamental DOM manipulation by selecting SVG elements and appending shapes like circles, rectangles, and an arc-based mouth. The code uses `d3.select`, `d3.arc`, and chained `transition.attr` calls to animate the eyebrow group’s vertical position. The face is drawn entirely with SVG, centered in a 960×500 viewport, and the animation runs continuously without external data.

Let's make a face with D3.js!

A smiley face drawn with SVG shapes animates its eyebrows in a looping motion. The example demonstrates basic DOM manipulation and transitions in D3.js v5, using `d3.select` to append circles, rectangles, and an arc-generated path for the mouth. Eyebrow movement is driven by chained `transition().duration()` calls that shift the group's `transform` attribute up and down. The face is centered via an SVG group with translated coordinates, and all styling is handled through inline attributes and a linked stylesheet.

Let's make a face with D3.js!

This example shows a smiley face drawn with SVG circles, rectangles, and an arc for the mouth. Its eyebrows bounce up and down repeatedly in an animated loop. The code demonstrates fundamental DOM manipulation with D3.js v5, using `select`, `append`, and chained `transition().duration()` calls to animate the eyebrow group’s transform. The face uses hardcoded dimensions, no external data, and renders entirely through SVG primitives within a 960x500 canvas.

Let's make a face with D3.js!

This example uses D3.js to construct a smiley face from basic SVG shapes, including circles for the eyes, rectangles for the eyebrows, and arc-generated paths for the mouth and nose. The code demonstrates fundamental DOM manipulation by selecting an SVG element and appending grouped elements with explicit coordinate transforms. Animated behavior is implemented through chained `transition` calls, moving the eyebrow group upward and back down over two one-second intervals. The visualization relies on D3’s `select`, `arc`, and transition APIs to show how static shape creation and simple attribute animation work together.

Let's make a face with D3.js!

An animated smiley face is built from basic SVG shapes, with eyes that blink and eyebrows that raise and lower in a looping transition. The example demonstrates fundamental D3.js DOM manipulation by selecting the SVG canvas, appending a group, and positioning circles, rectangles, and a path for the mouth. Using chained `transition()` calls, the code animates the eyebrow’s transform attribute and the eye’s radius over two-second durations. The mouth is drawn with D3’s `arc` generator, and all elements are centered via SVG group transforms.

Let's make a face with D3.js!

A smiley face drawn in SVG animates as its eyebrows bounce upward and settle back down. The example demonstrates fundamental D3.js DOM manipulation by constructing the face from appended shapes—circles for the eyes and head, rectangles for the eyebrows, and a path generated with the `arc` helper for the mouth. A chained `transition` with a two-second duration moves the eyebrow group twice, creating the animation. The code uses D3 v5 selections and attributes on a static SVG canvas.

Let's make a face with D3.js!

This example uses D3.js v5 to demonstrate fundamental DOM manipulation by building a stylized smiley face from SVG shapes. The face features animated eyebrows that move up and down via chained `transition().duration()` calls on a group element, creating a dynamic expression. The code explicitly constructs each facial component—circle for the face, two eye circles, rectangular eyebrows, and an arc-based mouth path—using D3’s `select`, `append`, and `attr` methods within an SVG canvas. The `arc()` generator calculates the mouth’s path with specified inner and outer radii.
