Let's make a face with D3.js!

This example shows a simple, animated smiley face built entirely with D3.js, where the eyebrows move up and down. It demonstrates fundamental DOM manipulation by selecting an SVG element and using D3’s data join and transition methods to update attributes over time. The code uses `d3.select` and `d3.transition` to animate the eyebrows, while the face itself is drawn with basic SVG shapes. The rendering is SVG-based within a 960×500 viewport, with styles defined in a separate CSS file. No external data source is used; the entire visual is generated programmatically.

A D3.js smiley face demonstrates basic DOM manipulation and chained transitions by animating raised eyebrows. Built from SVG primitives—circles for the face and eyes, rectangles for eyebrows, and an arc-generated path for the mouth—the code uses d3.select and d3.arc with explicit positional variables. The eyebrows move via transition().duration(2000) calls that shift the group’s transform attribute between two vertical offsets, creating a repeating motion. The example uses d3.v5 and renders entirely in SVG within a fixed 960x500 viewport.

A D3.js tutorial demonstrates fundamental DOM manipulation by building a smiley face with animated eyebrows. The example shows an SVG face whose eyebrows move dynamically, illustrating how D3 selects and modifies elements. The code uses `d3.select`, `append`, and `attr` to construct the face from SVG circles and paths, then applies transitions to adjust eyebrow positions. It relies on D3 v5, rendering everything as SVG within a 960x500 viewport, with accompanying CSS for styling and layout. The dataset is implicit—the face geometry is hardcoded rather than loaded from external data.

This example uses D3.js to build a smiley face whose eyebrows animate. The code selects an SVG element, sizes it to the full browser window, and appends a rounded rectangle as the background. It demonstrates fundamental DOM manipulation by chaining D3 methods like `select` and `append` to create the face’s parts, with the eyebrow movement driven by simple data-driven updates in the same SVG structure. The project relies on D3 v5 and renders entirely as SVG.

This example creates a smiley face whose eyebrows move, demonstrating fundamental DOM manipulation with D3.js. The face is drawn as SVG elements within a 960-by-500 canvas, and the animation cycles the eyebrows' positions through a looping interaction. The code uses D3’s selection and transformation methods to update the eyebrow elements’ attributes dynamically, relying on the `d3` library (v5.9.2) loaded from a CDN, with the page styling defined in a separate CSS file. The visual output is rendered entirely in vector graphics, and the movement is driven by JavaScript logic in the bundled script.

A smiley face is drawn as an SVG graphic, with animated eyebrows that move up and down. The example demonstrates fundamental DOM manipulation with D3.js by selecting an `svg` element and using the `arc` generator from the `d3` module to create the face’s shapes. The code reads the SVG’s height and width attributes via `attr` and parseFloat, and browses over a simple dataset to bind elements. Rendering uses SVG paths, with styles applied through an external stylesheet that hides page overflow.

Let's make a face with D3.js!

This example demonstrates basic D3.js DOM manipulation by building a smiley face with animated eyebrows. The SVG circle face, eyes, and rectangular eyebrows are appended to a centered group element, while the mouth is drawn using the `d3.arc` path generator. Eyebrow movement is achieved through chained `transition` and `.attr` calls that shift the group’s transform over two-second intervals. The code relies on D3 v5 selections and transitions, rendering entirely as animated SVG without external data sources.

Let's make a face with D3.js!

This example demonstrates fundamental D3.js DOM manipulation by creating an interactive smiley face with moving eyebrows. The face is rendered as SVG elements, and the eyebrows animate using D3’s `transition` and `attrTween` methods. The code leverages `d3.select` and `.append` to build the shape, while a YouTube video embedded in the README explains the process. The visualization uses `d3.v5` and is styled with external CSS, showing how D3 can handle simple, non-data-driven graphics.
