This example uses the D3.js library to draw a stylized smiley face entirely with SVG primitives. The code sets up a canvas, then builds facial features—a yellow circle, two eyes, eyebrows, a nose, and a mouth—using `circle`, `rect`, and `path` elements. Key D3 APIs include the `select` function to target the SVG root and the `arc` generator to construct the curved paths for the nose and mouth. A `.transition().duration(2000)` animation moves the right eyebrow downward over two seconds, while the left eyebrow remains static. All rendering is handled through SVG.

Let's make a face with D3.js!

A smiley face rendered in SVG uses D3.js to demonstrate fundamental DOM manipulation and animation. The code builds the face from primitive shapes—a yellow circle for the head, black circles for the eyes, a path for the mouth—and positions them via group transforms. Two animated eyebrows, implemented as rectangles, shift vertically using chained `transition() .duration(2000)` calls. The example reads SVG dimensions with `parseFloat`, uses helper methods like `select`, `append`, and `attr`, and draws the mouth with the `arc()` shape generator from D3's shape module.

Let's make a smiley face with D3.js

This example creates a smiley face from basic SVG shapes using D3.js, drawn on a 960×500 canvas. The face consists of a yellow circle with a black stroke, two eyes, rectangular eyebrows, and a mouth created with D3’s `arc` function. The eyebrows animate by chaining two `transition().duration(2000)` calls, moving them down and then back up over four seconds. The code uses D3 v5 selections (`select`, `append`) and attribute setters to position elements via transforms.

Let's make a face with D3.js!

This example demonstrates fundamental D3.js DOM manipulation by constructing an animated smiley face from SVG shapes. The face consists of a yellow circle head, two dark eyes, rectangular eyebrows, and an arc-based mouth, all positioned relative to an SVG group centered on the canvas. Using d3 selection and transition methods, the eyebrows perform a repeated up-and-down motion over two-second intervals. The code relies on d3.select, d3.arc for the mouth path, and chained transition.attrTween (via transition.attr) to animate the eyebrow group’s vertical offset, showcasing basic data-driven document updates without any external dataset.

Let's make a face with D3.js!

This example demonstrates fundamental D3.js DOM manipulation by constructing a smiley face from SVG shapes, with a gentle animation of its eyebrows. The code builds a yellow circle head, eyes, and a mouth using D3’s `select`, `attr`, and an `arc` generator for the path. The eyebrow rectangles transition vertically via chained `transition().duration(2000)` calls, moving them down and back up. It uses D3 v5, rendering to a static SVG canvas with no external data, focusing purely on programmatic element creation and animation.

Let's make a face with D3.js!

This example uses D3.js to construct a simple animated smiley face in SVG. The code builds the face from basic shapes—a yellow circle for the head, two eyes, eyebrows, and an arc-based mouth—and demonstrates D3's DOM manipulation and transition API. The eyebrows animate by moving up and down via chained `transition().duration(2000)` calls on the SVG group containing the rectangles, shifting the group's transform attribute. The visualization uses `d3.select` and `d3.arc` to generate the mouth path, with all elements centered in a 960-by-500 canvas.

Let's make a face with D3.js!

This example demonstrates fundamental D3.js DOM manipulation by building a smiley face from SVG elements, with animated eyebrows that move up and down. The code uses D3 selections to append a yellow circle for the head, circles for the eyes, rectangles for the eyebrows, and an arc-generated path for the mouth. It applies `transition` with a two-second duration to animate the eyebrow group’s vertical position, showcasing data-driven document updates. The rendering uses SVG within a 960x500 viewport, driven entirely by D3’s `select` and `arc` APIs.

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!

A D3.js example demonstrates fundamental DOM manipulation by constructing a yellow smiley face with animated eyebrows from SVG shapes. The code appends circles, rectangles, and an arc path to an SVG group, using D3’s selection API and the `arc` generator for the mouth. The right eyebrow transitions downward over two seconds via `transition().duration(2000)`, while all elements are positioned with static attributes. The example showcases basic data-driven document manipulation with D3 v5, using inline SVG rendering and no external data source.
