This visualization draws a smiling face using D3.js in an SVG canvas. A yellow circle forms the head, with black circles as eyes and a curved arc path as the mouth. The eyebrows, rendered as rectangles, animate upward and then back down using chained `transition().duration(2000)` calls. The code uses the `select`, `append`, and `arc` APIs from D3 v7 within a React framework, manipulating SVG attributes directly.

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.

Make a face with D3.js

A D3.js animation renders a simple smiling face from geometric SVG shapes: a yellow circle for the head, two eyes, two rectangular eyebrows, and a mouth drawn with the `d3.arc` path generator. The eyebrows animate vertically via chained `transition().duration()` calls, moving down 50 pixels and back, while the face remains centered using SVG group transforms. The code imports `select` and `arc` from D3 v5, and the visualization runs inside a React-free HTML page with an SVG canvas.

D3.js demo

This example visualizes a smiling face constructed entirely from basic SVG shapes using D3.js version 7. The code selects an SVG element and appends a yellow circle for the face, two black circles for eyes, and a curved path for the mouth using the `d3.arc` API. The visualization demonstrates fundamental D3 selection and data-joining techniques within a React framework, with the SVG dimensions derived directly from the element's attributes.

Let's make a face with D3.js!

A smiling yellow face is drawn with SVG, using D3.js to generate circles for eyes and an arc for the mouth. The animated eyebrows, rendered as rectangles, move up and down via chained `transition` calls on a group element. The code imports `select` and `arc` from D3 v5 and runs within a React framework, with the SVG canvas sized 960 by 500 pixels. Transforms center the face and position facial features relative to the middle of the canvas.

Draw face with D3.js

A smiling face drawn with D3.js appears as a yellow circle with black-outlined eyes, animated eyebrows, and a crescent mouth. The SVG-based visualization uses D3 selections to append shapes, including rect elements for eyebrows that transition vertically over two-second intervals. The mouth is rendered with d3.arc(), while circle positioning and transforms center the face within an SVG. D3 v6 powers the animation and shape construction in this React-free starter example.

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.

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 uses D3.js to draw an animated face from basic SVG shapes. A yellow circle forms the head, with black circles for eyes and rectangular eyebrows that transition vertically over time. The mouth is built from arc paths generated with D3’s `arc` function. All elements are grouped and translated to the center of the 960x500 SVG canvas, and the code runs within a React starter template.
