Let's make a face with D3.js!

A D3.js tutorial demonstrates fundamental DOM manipulation by building a smiley face with animated eyebrows in an SVG canvas. Using D3's `select` and `append` methods, the code creates and styles SVG circles and other elements dynamically. The example relies on D3 v5's modular imports and shows how to set attributes like radius and position through chained method calls. The accompanying video explains the step-by-step process, while the working code is rendered directly in the browser using standard SVG elements within a 960×500 viewport.

This example demonstrates fundamental DOM manipulation with D3.js by constructing a smiley face from basic SVG shapes. The code selects the SVG element and appends a circle with a radius of 200 pixels, while the accompanying stylesheet hides body margins and overflow. Using D3 v5’s `select` and `append` methods, the visualization shows how to programmatically create and style SVG elements, with related video content explaining animated eyebrow movement.

D3.js builds a simple, interactive SVG smiley face whose eyebrows move. The example demonstrates core DOM manipulation by appending and positioning SVG shapes, including circles, a polygon, and a path. It uses D3's `select`, `attr`, and `append` methods to construct the face, while an `arc` shape generates the mouth. A linked video tutorial accompanies the code. The face is centered using an SVG group with a translate transform, and the styling is defined in a separate CSS file.

This example demonstrates fundamental DOM manipulation with D3.js by constructing a smiley face from SVG primitives. A single circle is appended to the SVG canvas and positioned at the center with a radius of 225 pixels, though its fill is left undefined. The code uses the D3 v5 selection and append methods (`select`, `append`) to build the shape step-by-step, revealing how D3’s API interacts with SVG elements. The static face serves as a starting point for interactive features shown in an accompanying video.

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.

This example demonstrates fundamental DOM manipulation with D3.js by building a smiley face in an SVG canvas. The code selects the `<svg>` element, retrieves its width and height attributes, and positions a circle at the center using those dimensions. It uses D3’s `select` method and chained attribute setters like `attr(‘r’)`, `attr(‘cx’)`, and `attr(‘cy’)` to control the face’s radius and coordinates. The rendering relies on D3 v5 with SVG output, and the accompanying video highlights interactive eyebrow movement.

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 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.
