This example demonstrates how to construct a simple smiling face using D3.js v6 primitives. The visualization builds the face from an SVG circle for the head, two additional circles for eyes, and an arc-generated path for the mouth, all positioned within a translated group. The mouth uses an animated transition over 2 seconds to shift its vertical position, showcasing D3’s built-in transition capabilities. The code relies on D3’s `select`, `append`, and `arc` APIs, rendering entirely through SVG elements without external data sources.

D3 intro

This example renders a smiling face using D3 v5 and React, with SVG elements including circles, rectangles, and paths. The face is centered on the screen, and the eyebrows animate upward and downward using chained `transition()` calls with a two-second duration each. The code leverages D3’s `select`, `arc`, and `line` APIs to construct the mouth and nose shapes, while static SVG attributes define the eyes and overall composition. The visualization demonstrates basic SVG drawing and animation within a React framework.

Let's make a face with D3.js!

A D3.js example assembles a smiling face from primitive SVG shapes: a yellow head circle, two eye circles, rectangular eyebrows, and a mouth formed by an annulus arc path. The scene is vertically centered using a group translation, and the right eyebrow demonstrates the library's chained transition API by animating its vertical position in two sequential 2-second movements. The code imports `select` and `arc` from D3 v5 and applies SVG attributes directly within a React-based build.

Let's make a face with D3.js

This example builds a smiling face out of basic SVG shapes using D3.js. The code creates circles for the face and eyes, rectangles for eyebrows, and an arc-generated path for the mouth, all positioned within a centered group. It uses D3’s `select`, `attr`, `append`, and `transition` with `duration` to animate the eyebrows moving up and down. The rendering relies on an SVG element defined in HTML, and the fixed dimensions (960 by 500) are read via `parseFloat(svg.attr(...))`. The face is composed entirely from hardcoded values, with no external data.

Let's make a face with D3.js!

This example demonstrates fundamental DOM manipulation with D3.js by building a smiling face from scratch. The code constructs the face using basic SVG shapes—circles for the eyes, rectangles for the eyebrows, and a path generated with the `arc` generator for the mouth—all centered within an SVG canvas. A sequential `transition` on the eyebrows group animates the eyebrows upward and back over two seconds each way, creating a simple expressive motion. The script uses D3’s `select` and `append` to build the hierarchical structure, and the animation relies on D3’s built-in transition system.

Intro to D3: Happy Face

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.

Make a Face with D3

This example demonstrates how to construct a smiling face using D3 version 6 and React. It builds the face from SVG shapes—a yellow circle for the head, two black circles for eyes, and a path for the mouth—all centered and scaled with data from the SVG's width and height attributes. The eyebrows are animated using D3's `transition` API, moving them vertically over two sequential 2-second intervals. The code leverages D3's `select`, `arc`, and `attr` methods, along with React's `render` function to manage the SVG output.

Let's make a face with D3.js

This example builds a simple cartoon face from basic SVG shapes, including circles for the head and eyes, rectangles for eyebrows, and a path for the mouth. The face is grouped and centered within the SVG canvas. The animation is driven by D3 transitions, which sequentially move the eyebrows downward over two-second intervals. The code uses D3 v5's selection, arc, and transition APIs to construct and animate the elements, with the mouth generated using the `d3.arc` geometry generator to create a curved path.

Let's make a face with D3.js!

This example demonstrates fundamental DOM manipulation with D3.js by building an animated smiley face out of SVG shapes. The code uses `d3.select` to append a circle for the head, two circles for eyes, rectangles for eyebrows, and an `d3.arc()` path for the mouth. D3 transitions animate the eyebrows upward and back over four seconds. The example uses D3 v5 and relies on simple attribute setters like `.attr()` to position each element.
