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

This example demonstrates basic HTML and D3.js v4 data binding through an interactive button that executes D3 selections and data joins. The page contains a sandbox with four paragraphs, and clicking the button applies D3 methods like `d3.select`, `.style`, `.text`, and `.data().enter().append()` to modify existing text and append new paragraphs from a small array. The code also includes a checklist for guided exercises, with styling applied via CSS selectors and checkbox states. It serves as a hands-on workshop introducing core D3 selection and data-binding patterns.

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

This interactive tutorial demonstrates fundamental D3.js data binding techniques within a sandboxed HTML page. Users click a button to trigger JavaScript that selects existing paragraph elements, modifies their text and font size, then uses `d3.selectAll` with `.data()` and `.enter()` to append new paragraphs from a two-element string array. Clicking any newly appended paragraph changes its text and color via D3’s click event handler. The page also includes a checklist of coding exercises, with D3 used to programmatically check off items when the button is pressed.

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.

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

This interactive tutorial demonstrates core d3.js concepts through a button-triggered sandbox. The interface presents four existing paragraphs and a button that, when clicked, executes JavaScript using the d3.select and d3.selectAll APIs to modify their styles—changing font size and text content. The code then illustrates data binding by mapping a hardcoded array of two strings to new paragraph elements via d3's data(), enter(), and append() methods. The example also includes an exercise checklist for learners, though the checkboxes are not wired to the d3 logic.

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

This example demonstrates the fundamentals of D3 v4 data binding through an interactive button that runs JavaScript to manipulate paragraphs. It shows how to select existing elements with `d3.select` and `sandbox.selectAll`, modify their styles and text, then bind an array of data to new paragraph elements using the `.data()`, `.enter()`, and `.append()` pattern. The HTML includes a sandbox container with four initial paragraphs and a button triggering the `runCode` function, while d3’s `style` and `text` methods handle the visual updates. The page also features a checklist exercise for learners to practice these D3 concepts.

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.

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

This interactive exercise demonstrates basic D3.js data binding and manipulation on a webpage. The page displays a button that, when clicked, runs JavaScript using D3 to select all elements with the class "standard" and changes their font size and text. It also shows how to bind an array of two strings to new paragraph elements, appending them to the DOM, and attaching click handlers that log messages and alter text. The example uses the D3 version 4 API, including `d3.selectAll`, `.data()`, `.enter()`, `.append`, and `.classed`, to programmatically modify HTML content.
