This example demonstrates fundamental D3.js DOM manipulation by building a smiley face from circles whose eyebrows shift. It shows how the data-join pattern works step by step: first, five red apples are appended as circles using `selectAll`, `data`, and `enter`, then the array is mutated and re-joined to reveal how `exit` selects and recolors removed elements. The code uses D3 v5’s `select`, `range`, and the SVG coordinate system, rendering into an inline SVG canvas. It provides a hands-on introduction to enter, update, and exit selections without any real dataset.

Let's make a face with D3.js!

This example demonstrates fundamental DOM manipulation in D3.js by rendering a smiley face from an array of fruit objects. The visualization starts with five red circles representing apples, positioned horizontally across an SVG canvas, then removes the last fruit from the data array, causing the corresponding circle to turn black through the exit selection. The code uses D3’s `select`, `range`, data joins with `enter` and `exit` methods, and SVG circle attributes to show how data bindings drive visual updates. The rendering is entirely SVG-based, with a fixed 960×500 viewport.

Let's make a face with D3.js!

This example demonstrates fundamental DOM manipulation with D3.js by building a smiley face from SVG circles, with animated eyebrows that move. The code uses D3 v5’s `select`, `range`, and data joins to bind an array of five fruit objects to circles, setting position and fill attributes. The rendering is pure SVG, created through `.enter().append('circle')` on an empty selection. The eyebrows are implied through the data structure, though the visible output focuses on the static face layout.

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.

Let's make a face with D3.js!

This example demonstrates fundamental DOM manipulation with D3.js by constructing a smiley face from basic SVG shapes, including a red circle head, eyes, and a mouth. The visualization showcases animated eyebrows that move up and down using D3 transitions, with the `select` and `append` APIs building the SVG hierarchy. The code uses `d3.select` to target the SVG element, `attr` to set properties like coordinates and dimensions, and `arc` to generate the mouth path. The animation runs through chained `transition()` calls with specified durations, highlighting D3's ability to animate SVG attributes over time.

Let's make a face with D3.js!

This example demonstrates fundamental DOM manipulation with D3.js v5 by constructing a smiley face out of basic SVG shapes. The code uses `d3.select`, `d3.append`, and chained `.attr()` calls to create a yellow circle, two eye circles, a mouth path drawn with `d3.arc()`, and a rectangular eyebrow that animates vertically via a pair of `transition().duration()` calls, moving down and back up repeatedly. No external data is used; the visualization relies purely on hardcoded geometry and SVG rendering.

Let's make a face with D3.js!

This example demonstrates how to construct a smiley face using D3.js version 5, focusing on fundamental DOM manipulation with SVG elements. The code explicitly appends a group and a circle element to the SVG canvas, positioning them at the center of a 960×500 viewport. It uses the `select` and `append` methods from the `d3` namespace to build the geometric face outline, with a transparent fill and black stroke. The visualization is purely programmatic, with no external data source, and includes a static smile path defined directly in the HTML markup.

Let's make a face with D3.js!

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.

Let's make a face with D3.js!

This example demonstrates fundamental DOM manipulation and animation with D3.js by building a smiley face from SVG shapes. A red circle forms the head, with appended circles for eyes and rectangles for eyebrows, while a mouth is drawn using the `arc` generator. The code uses `selection.append` and `transition.attr` to move the eyebrow group up and down over two seconds. All elements are positioned relative to a centered `g` container, using D3 v5’s modular `select` and `arc` imports, with the SVG defined statically in HTML.
