This example demonstrates fundamental DOM manipulation with D3.js by building a yellow smiley face from SVG primitives, complete with eyes, eyebrows, and a mouth. The eyebrows animate up and down using chained `transition().duration()` calls, shifting the eyebrow group’s `transform` attribute over two seconds. The code uses `d3.select` and `d3.arc` from the D3 v7 library, setting positions via `attr` and leveraging SVG circles, rectangles, and a path for the arc-based mouth.

Let's make a face with D3.js!

This example illustrates fundamental DOM manipulation with D3.js by building a smiley face from SVG primitives. A yellow circle forms the head, with two eye circles, a mouth path created using the `arc` generator, and rectangular eyebrows. The animation uses chained `transition()` calls to animate the eyebrow group's `transform` attribute upward and then back down over two seconds each, creating a simple moving expression. The code relies on `svg.append`, `.attr`, and D3's selection and transition APIs, rendering entirely through SVG without external data.

Let's make a face with D3.js!

This example demonstrates fundamental D3.js DOM manipulation by building a yellow smiley face with animated eyebrows. The face is constructed entirely with SVG elements, including circles for the eyes, rectangles for the brows, and a mouth path generated with the `d3.arc` shape generator. The eyebrows perform a continuous up-and-down motion using chained `transition` and `duration` methods. The code imports `select` and `arc` from D3 v5, applies attributes directly to SVG shapes, and uses template literals for transform translations.

Let's make a face with D3.js!

This example uses D3.js version 5 to construct a yellow smiley face with eyes, eyebrows, and a mouth directly in an SVG. It demonstrates fundamental DOM manipulation by selecting elements, appending shapes, and applying attributes. The code uses `d3.select` and `d3.arc` to generate the mouth path, while a two-stage `transition()` chain animates the eyebrows upward and then back to their original position over 4 seconds.

Let's make a face with D3.js!

This example demonstrates fundamental DOM manipulation with D3.js by building a yellow smiley face from SVG shapes, including eyes, eyebrows, and an arc-based mouth. The code uses `d3.select`, `d3.arc`, and `transition.attr` to animate the eyebrows moving up and down over a two-second cycle. Rendered in an SVG canvas, it highlights how D3 v5 binds data and updates attributes directly, with all elements positioned relative to a centered group.

Let's make a face with D3.js!

This example demonstrates fundamental DOM manipulation with D3.js by constructing a smiley face from SVG primitives: a yellow circle, two eyes, a mouth drawn with `d3.arc`, and rectangular eyebrows. The face is centered in an SVG canvas via a `g` element and coordinate transforms. The eyebrows animate using chained `transition().duration()` calls, moving up and down over two-second intervals. The code relies on D3 v5 selection, attribute setting, and transition APIs to mutate SVG elements directly.

Let's make a face with D3.js!

This example demonstrates fundamental DOM manipulation and animation with D3.js by constructing a smiley face from SVG shapes and animating its eyebrows. A yellow circle forms the head, with eyes, rectangular eyebrows, and an arc-based mouth positioned using D3 selections and attribute setters. The code uses d3.select, d3.arc, and chained transitions with .transition().duration() to move the eyebrow group up and down over two 2-second cycles. All elements are appended to an SVG container, with positioning handled via transform attributes.

Let's make a face with D3.js!

This example demonstrates fundamental DOM manipulation with D3.js by building an animated smiley face from SVG shapes. A yellow circle forms the head, with eyes, eyebrows, and a mouth added as separate elements. The code uses d3.select and append to construct the face, then applies chained transitions to move the eyebrows up and down repeatedly. The mouth is drawn using d3.arc with specified inner and outer radii and angles. All shapes are positioned relative to a centered group, with animation running for two seconds per eyebrow movement cycle.

Let's make a face with D3.js!

This example demonstrates fundamental DOM manipulation with D3.js by constructing a cheerful yellow smiley face from SVG primitives and animating its eyebrows. The code uses `d3.select`, `d3.append`, and `d3.arc` to build the face's circles, rectangles, and mouth path within a centered group. A `transition` with a two-second duration moves the eyebrow group up and down, creating a looping eyebrow-raising effect. The rendering is entirely SVG-based, with coordinate calculations in plain JavaScript driving the layout.
