A yellow circle face with eyes, eyebrows, and an arc-shaped smile demonstrates fundamental D3.js SVG rendering and animation. The code builds the face using D3 selections and shape generators, including `d3.arc()` for the mouth path, while positioning elements with SVG `transform` attributes derived from the viewport dimensions. Eyebrows animate through chained `transition().duration()` calls, moving them down and then up over four seconds. The example uses D3 v7 within a React project, drawing on a static SVG canvas with no external data.

Let's make a face with D3.js!

A smiling face is rendered as a yellow circle with black eyes, animated eyebrows, and a curved mouth built from an arc path. The code uses D3 v5 selections to append SVG shapes, and chains `transition().duration()` calls to move the rectangular eyebrows up and down. The mouth is generated with the `d3.arc()` helper, specifying inner and outer radii and angular extents. Static circle elements define the face and eyes, while the animation runs once on load in a React framework.

Let's make a face with D3.js!

This example draws a smiling yellow face out of SVG shapes using D3.js v5. It constructs a circle for the head, two circles for eyes, rectangles for eyebrows, and an arc path for the mouth, all centered on an SVG canvas. The eyebrows animate upward and back down over four seconds using chained `transition` calls with a two-second duration each. The code relies on D3’s `select` and `arc` functions to build the scene entirely from static attributes, with no external data source.

Let's make a face with D3.js!

A cheerful yellow face is drawn with D3.js, featuring circular eyes, rectangular eyebrows, and a curved mouth, all rendered as SVG elements. The eyebrows animate up and down over two seconds using D3 transitions. The code uses `d3.select`, `d3.arc`, and SVG shape methods like `append`, `attr`, and `transition` to build the face within a 960x500 viewport, centering the elements with a group transform.

Let's make a face with D3.js

A smiling face is drawn as a yellow circle with two eyes, animated eyebrows, and an arc-shaped mouth, all rendered in SVG. The animation uses D3 transitions to move the eyebrows up and down over two seconds. The code leverages `d3.select`, `d3.arc`, and SVG `circle`, `rect`, and `path` elements within a fixed 960×500 viewport, with the face centered via a group transform.

Make a face with D3.js

A yellow face built from SVG primitives sits centered in the canvas, with two circles for eyes, two rectangles as eyebrows, and a path-based mouth using `D3.arc`. The eyebrows animate upward and then back down over two seconds using D3’s `.transition().duration()` API, creating a subtle, repeated motion. The code imports `select` and `arc` from D3 v6 within a React framework, and renders entirely through SVG elements positioned via transforms.

D3.js Intro

This example displays a simple yellow smiley face rendered in SVG, with animated eyebrows that move up and down over time. The face is constructed using D3.js v5 selection methods to append circles, rectangles, and an arc-generated mouth path. The code uses the `arc` API from D3 to define the mouth shape, while `transition` and `duration` create the eyebrow animation. The static SVG container is sized at 960 by 500 units, and the face is centered using a translated group element.

Let's make a face with D3.js!

A smiling yellow face is drawn with SVG circles, rectangles, and an arc path, then animated when its eyebrows jump upward and settle back down. The example uses D3.js version 5 selections and transitions, including `transition().duration()` to move the eyebrow group's `transform` attribute. A React starter variant is mentioned in the README, though the core code relies on D3’s `select`, `arc`, and attribute manipulation to compose the face from basic geometric shapes.

Let's Make a Face With D3.js !

A yellow circle face with eyes, eyebrows, and a mouth is drawn on an SVG canvas. The facial features are comprised of D3.js shapes, including circles for the eyes and a path generated with `arc()` for the smile. An animation uses `transition()` with a 2000-millisecond duration to repeatedly raise and lower the eyebrows, creating a surprised expression. The example demonstrates D3's SVG rendering and animation APIs within a React framework.
