This example demonstrates how the D3 `data()` method binds an array of strings to a selection of four `<h3>` elements, mapping each array entry to a corresponding DOM element. The code uses D3 v5 and the selection’s `.text()` callback to display each lyric along with its index, showing that the array order directly matches the element order in the page. The data array contains four bird-themed phrases, and the text update occurs without any animation or additional D3 layout features, focusing solely on the fundamental data join.

d3 datum()

This example demonstrates how the `datum()` method binds a single piece of data to multiple DOM selections at once. The page contains four empty `<h3>` elements, and the script selects them all with `d3.selectAll('h3')`, then calls `datum('i am a little bird')` to attach the string to each element. Using the `.text()` method with an accessor function, it renders both the bound value and the element’s index, showing that the same data is shared across all selected nodes. The code uses D3 v5 and plain JavaScript in a simple HTML file.

Learn d3.js

This example demonstrates the fundamental data-binding pattern in D3.js by binding an array of six numbers to paragraph elements and displaying each value as text. The code uses `d3.select` to target the body, then chains `selectAll('p')`, `.data()`, `.enter()`, and `.append('p')` to create one paragraph per data point. The `.text()` method with a function returns each datum, rendering the numbers 1 through 6 on the page. It relies on D3 v4’s core selection and data-join APIs within a minimal HTML setup that loads the library from a CDN.

Learn d3.js

This example demonstrates the basic data-binding workflow of D3.js version 4, using a static array of five numbers as the dataset. The code shows how `d3.select`, `selectAll`, `.data()`, and `.enter()` work together to create one paragraph element per data point. It appends `<p>` tags to the body and sets their text content with a callback function that returns each value. The visualization is minimal, focusing on the core enter selection pattern rather than scales or axes.

d3 JS

This example demonstrates the basic D3.js pattern for binding an array of data values to HTML elements and appending new elements to the DOM. Using the `d3.select`, `selectAll`, `data`, `enter`, and `append` methods, it creates three `<p>` paragraphs inside a `<div>`, each displaying its corresponding data value as text. The code relies on the v5 release of the d3.js library, loaded via a CDN link in the `index.html` file, and uses an `app.js` script to perform the selection and binding operations.

D3.js!

This example demonstrates the fundamental data-join pattern in D3.js, where an array of numbers [1, 2, 3] is bound to a selection of paragraph elements. Using `d3.select`, `selectAll`, `data`, `enter`, and `append`, it creates three `<p>` elements inside a `<div>`, with each paragraph’s text set to the corresponding data value via `.text(dta => dta)`. The code runs in a React environment while loading the D3 v7 library from a CDN, highlighting how to mix D3’s imperative DOM manipulation with a minimal HTML page structure.

Learn d3.js

This example demonstrates how to bind an array of five numbers to paragraph elements using D3.js version 4. It shows the core data-join pattern, where the `d3.select` and `selectAll` methods target the body, while `.data()`, `.enter()`, and `.append()` create new `<p>` elements for each value. The `.text()` function then populates each paragraph with its corresponding number from the dataset. The code runs within a minimal HTML page that loads D3 from the official CDN.

Untitled

This example demonstrates how D3 can bind data to pre-existing HTML list items and update them dynamically. The visualization shows five initial values displayed as text within `<li>` elements, with a button that triggers removal of the fourth data point. The code uses D3 v4’s selection API, including `.data()`, `.text()`, and `.exit().remove()`, all inside an HTML page with inline JavaScript. It relies on the `d3.select` and `d3.selectAll` methods to manipulate the DOM.

Let's make a face with D3

A small web page demonstrates D3.js data binding by attaching an array of five numbers to a collection of empty paragraph elements. The code uses `d3.selectAll('p')` to select all paragraphs, chains the `.data()` method with the array, and applies `.text()` to output each value into its corresponding paragraph. The example also logs both the data and its index to the browser console, showing the iterative binding process. The HTML structure includes a series of empty `<p>` tags and loads D3 version 6 from a CDN.
