Let's make a face with D3.js!

A smiley face rendered as an SVG animation demonstrates core D3.js DOM manipulation. The code appends geometric elements—circles for the face and eyes, rectangles for eyebrows, and a path built with `d3.arc` for the mouth—onto an SVG canvas. Chained `transition().duration()` calls animate the eyebrow group’s vertical position, moving them up and down over four seconds. Using `d3.select` to create and transform elements, this example highlights how D3 binds data-independent shapes and drives simple timeline-based motion without external data sources.

D3.js Demo

This example draws a simple animated face using D3.js v5, rendering shapes in SVG. It uses `d3.select` to build a green circle for the face, two eyes, a mouth created with `d3.arc`, and rectangular eyebrows. A `transition().duration()` animation moves the eyebrows up and down. The code also imports `select` and `arc` as ES6 modules from the D3 library.

Let's make a face with D3.js!

A simple D3.js face built from basic SVG shapes—a yellow circle for the head, two eyes, animated eyebrows, and an arc-based mouth—is centered on a blank canvas. The eyebrows continuously move up and down using chained `transition()` calls over two seconds each. The visualization demonstrates fundamental D3 v5 concepts, including `select` for DOM access, `attr` for positioning, and the `arc` generator to create the mouth path, with all elements drawn as SVG primitives.

Let's make a face with D3.js!

This example creates a smiling face from basic SVG shapes, including a red circle head, two eyes, rectangular eyebrows, and a mouth drawn with an arc path. The main visual behavior is an animated eyebrow movement, achieved by applying a two-stage D3 transition to the eyebrow group's transform attribute over four seconds. The code demonstrates fundamental D3.js v5 DOM manipulation by using the selection, append, and attr methods to build the SVG structure, while the transition method handles the animation loop.

Let's make a face with D3.js!

This example builds a smiling face from basic SVG shapes using D3.js, with animated eyebrows that move up and down in a looping transition. The code selects an SVG element, centers a group, and appends a circle for the head, circles for eyes, rects for eyebrows, and a path for the mouth generated with the `d3.arc()` helper. Using `d3.transition()` and `.duration(2000)`, the eyebrows shift vertically twice, creating a repetitive motion. The demonstration focuses on fundamental DOM manipulation—such as `.append()`, `.attr()`, and chained transitions—while rendering entirely in SVG with no external data.
