This example demonstrates introductory D3.js and JavaScript concepts from the D3 Cook Book, showing how to create reusable widget functions and manipulate DOM elements. It uses d3.select and d3.selectAll to target paragraphs and divisions, applying CSS classes to render colored boxes with red and blue backgrounds. The code also illustrates functional JavaScript patterns through a SimpleWidget constructor that chains methods like _headline and _description to build custom components. Data binding is shown through d3's .each method to append text elements within selected paragraphs.

MasteringD3js_Ch2 pt1

This example demonstrates four fundamental techniques for creating DOM elements with D3.js v5, adapted from a v3-era cookbook. It shows method chaining to append divs and paragraphs, the `selection.call` function to encapsulate creation logic, a custom initializer function passed to `.call()`, and finally, dynamic SVG element creation with bound data. The code uses `d3.select` (a corrected form of `d3.select`) and the enter/append pattern to build a simple bar-like structure of labeled boxes.

D3_CookBook(v5)_Ch2 pt2

Three HTML tables display financial transactions, with each table's rows styled differently through D3 selections. The example demonstrates raw DOM selection and manipulation using d3.select and .selectAll("tr") to target table rows, then applying CSS classes like "table-header" and "table-row-odd" based on row index. It shows how to filter row elements via a selection's .select(function(d, i) { ... }) callback, checking an element's position before assigning class attributes. The code adapts older D3 v3 patterns to D3 v5, highlighting changes in how raw selections and element references are handled.

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

This example demonstrates a hands-on D3 workshop exercise that introduces basic HTML structure, the D3.js v4 library, and fundamental data-binding concepts. It shows a sandboxed webpage with a button that, when clicked, triggers a JavaScript function to manipulate existing paragraph elements and append new ones based on an array of data. The code uses `d3.select` and `d3.selectAll` to target DOM elements, applies styles and text changes, and employs the data join pattern with `.data()`, `.enter()`, and `.append()` to create new paragraphs. It also attaches click event handlers to dynamically added elements, logging a message and altering their appearance, while the accompanying exercise checklist guides users through modifying the code to reinforce learning.

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 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 example demonstrates an interactive D3 v4 workshop that teaches basic HTML, d3, and data binding through a hands-on exercise. It shows a button that, when clicked, runs a d3 code snippet targeting paragraphs inside a sandboxed div, while a checklist outlines tasks like adding paragraphs, manipulating text, and binding arrays. The code uses d3.js v4, with d3.select and d3.selectAll to handle DOM selection and manipulation, plus event handling for button clicks. The visualization renders static HTML paragraphs as the primary data display, with the exercise structure guiding users through progressive coding challenges.

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.

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

This example demonstrates how to bind data to HTML elements using D3 v4. It features a sandbox with four paragraphs that, upon clicking a button, change their text and font size. The code then uses D3’s `selectAll`, `data`, and `enter` methods to append two new paragraphs from a simple array, with commented examples showing how to attach click handlers to modify text dynamically. The exercise section lists interactive checkboxes that can be toggled via D3’s property method.
