Let's make a face with D3.js!

A smiling face is drawn on an SVG canvas using D3.js, with eyebrows that move dynamically to create an animated expression. The example demonstrates fundamental DOM manipulation by selecting the SVG element via `d3.select`, reading its width and height attributes, and using D3's `arc` function to construct the facial features. The rendering is entirely vector-based, relying on SVG shapes styled through an external stylesheet. The interaction and motion are driven by D3's data-binding and attribute-update capabilities, highlighting the library's core strengths in programmatic visualization and animation.

A smiley face rendered in SVG responds to mouse movement by shifting its eyebrows, demonstrating fundamental DOM manipulation with D3.js. The example uses D3 v5’s `select` method to target the SVG element and the `arc` generator to draw the face’s curved features, such as the mouth. The visualization shows how D3 binds data to existing DOM nodes without requiring `.enter()` or `.append()`, focusing instead on updating attributes in response to user interaction. The face is built entirely through SVG shapes, with styling handled by an external CSS file.

This example shows a smiley face built from SVG shapes, with eyebrows that animate in response to the viewer’s actions. The code demonstrates fundamental DOM manipulation with D3.js v5, using `d3.select` and `d3.append` to create the face’s elements. It relies on the `d3.arc` generator for the mouth and applies simple transitions to move the eyebrows. The page reads the client’s viewport dimensions to size the SVG canvas, and styling is handled via an external stylesheet.

A smiley face rendered in SVG demonstrates basic D3.js DOM manipulation, with animated eyebrows that move to change the expression. The example uses D3 v5's `select` and `arc` functions to construct the facial features, building circles and arcs for the eyes, mouth, and brows within an SVG canvas. The code shows how D3 can directly create and update SVG elements through its data-binding and selection APIs, while the accompanying stylesheet hides page overflow for a clean, focused presentation.

A smiling face rendered as an SVG graphic uses D3.js to demonstrate fundamental DOM manipulation. The face’s eyebrows move dynamically, driven by JavaScript code that selects and updates SVG elements. The example leverages D3’s `select` and `arc` functions to construct and position the facial features. The visualization is built with D3 v5 and displayed in an HTML page with a 960 by 500 pixel SVG canvas, with the interaction logic contained in a separate `bundle.js` file.

A smiling face is drawn as an SVG, with animated eyebrows that move independently. The visualization demonstrates fundamental DOM manipulation with D3.js, using the `select` and `arc` functions from D3 v5 to construct the facial features. The page loads a 960 by 500 pixel SVG element and renders the face directly within it, with styles applied from an external stylesheet. The example serves as a simple, interactive introduction to building and updating SVG graphics with D3's data-driven approach.

A smiley face rendered in SVG responds to mouse movement by shifting its eyebrows. The example demonstrates fundamental D3.js DOM manipulation using `d3.select` and `d3.append` to build the face from circles and paths, with the `transform` attribute controlling its position. Eyebrow movement is driven by event handlers that update the `cy` attribute of SVG elements. All drawing uses SVG primitives within a single `<svg>` element, with no external data source.

A red D3.js smiley face is rendered in an SVG, with animated eyebrows that move to change its expression. The example demonstrates fundamental DOM manipulation by using `d3.select` to style the SVG background and dynamically update facial features. Built with D3 v5, the code relies on standard selection and attribute methods to drive the interactive animation, showing how to bind data to visual elements and create a playful, state-based face.
