This example demonstrates D3.js data binding by mapping an array of five names to dynamically created `div` elements. It shows how the `enter()` selection creates one element per data item, then uses a text function to display each name with its corresponding index. The visualization uses D3 v3’s `d3.selectAll`, `.data()`, `.enter()`, and `.append()` to bind and render the data, highlighting the core concept of joining data to DOM nodes. The rendered output is a simple list of numbered greetings, illustrating the fundamental data-join pattern.

d3js workshop - data binding

This example demonstrates D3.js data binding by mapping an array of five names to newly created `<div>` elements. It shows how data can drive the DOM, with each element displaying its corresponding value and a sequential number. The code uses `d3.selectAll('div')` to create an empty selection, `.data([...])` to bind the array, and `.enter().append('div')` to generate elements for each data point. Finally, `.text(function(d, i))` populates each div with the index and name, illustrating D3’s enter selection and data-driven updates.

d3js workshop - data binding

This example demonstrates data binding in D3.js, where an array of four names is joined to an empty selection of `<div>` elements using `d3.selectAll('div').data(...).enter()`. No visual output is rendered initially, as the `.append('div')` and `.text()` calls remain commented out, leaving the code as a starting point for a workshop exercise. The script loads D3 v3 from a CDN and shows how `.enter()` creates placeholder selections for each data item, with the actual text assignment to the bound data values commented out for participants to explore.

d3js workshop - data binding

This example demonstrates D3.js data binding through interactive selection and DOM manipulation. It shows how to target specific HTML elements using CSS-style selectors, with commented examples for selecting by element type, class, or ID, and updating their text content. The code also illustrates appending new elements to the DOM using `d3.select` and `.append()`. Using D3 v3, the visualization relies on core selection methods like `selectAll` and `text` to illustrate the framework’s binding capabilities, with the page containing two static divs and commented-out code that reveals potential interactions.

d3js workshop - data binding

This example demonstrates how D3 selections can target specific elements in the DOM using element type, ID, and class selectors. The page contains two visible divs with different identifiers, and commented code shows updated text for various selection strategies, such as `d3.selectAll('div.selectMe')`. It also illustrates appending new elements, where `d3.select('body').append('div')` adds a child to the document body. Built with d3.v3, the example relies solely on D3’s core selection and manipulation APIs, with no external data or rendering pipeline.

d3js workshop - data binding

This example demonstrates how D3 selections target and manipulate specific DOM elements, showing the difference between selecting all matching elements versus a filtered subset. It highlights how chained selection methods like `selectAll` and `select` work, along with class and ID selectors, to update text content or append new nodes. The code uses the D3 v3 library, loading it from a CDN, and applies methods such as `select`, `selectAll`, `text`, and `append` to bind data-driven changes to a simple HTML structure containing two divs. No external data source is used; the example relies on static HTML content within the page.

D3 Workshop: Part 1 - Basic HTML, d3, and Data Binding

This example demonstrates interactive data binding in D3.js v4, showing how to manipulate existing paragraphs and append new ones from an array. It uses D3's selection and data-join methods (`d3.select`, `selectAll`, `data`, `enter`, `append`) to update text and styles, plus click handlers to change content dynamically. The visualization includes a button that triggers the code and a checklist of exercises, all built with basic HTML and the D3 library loaded via CDN. The data source is a simple two-item array, `myData`, rendered as new paragraphs with class `newPara`.

D3 Workshop: Part 1 - Basic HTML, d3, and Data Binding

This interactive teaching example demonstrates D3 v4 data binding by transforming static HTML paragraphs when a button is clicked. It uses `d3.select` to target elements in a sandbox div, applying style and text changes to existing paragraphs. The code then demonstrates the enter selection pattern with `d3.selectAll().data().enter().append()` to create new paragraphs from a two-element array, binding data to each. These dynamically added paragraphs include click handlers that log to the console. The example also includes a checklist of coding exercises tied to the D3 concepts shown, making it a hands-on workshop for learning basic data joins and selections.

Learn d3.js

This example shows a minimal introduction to D3.js data binding using an array of five numbers. A static SVG container is set up in the HTML, while the JavaScript selects the body, binds the dataset to paragraph elements, and appends them with the corresponding text values. The visualization demonstrates the core `data()`, `enter()`, and `append()` pattern from D3 v4, alongside the use of `select()` and `text()`. It does not include interactivity or dynamic updates, serving purely as a basic learning exercise.
