This example demonstrates how to dynamically add an HTML element to a web page using D3.js. The code selects the body element and appends a new paragraph containing the text "New paragraph!" through D3's `select` and `append` methods. It uses the D3.js version 4.5.0 library, imported via a script tag, and is rendered as an animation in the browser. The page also includes commented-out alternative approaches and a stylesheet definition for a message class.

04. D3 Paragraphs

An animation demonstrates how D3.js can dynamically create HTML paragraphs from a dataset. The script defines an array of five numbers and uses the `d3.select` and `data` methods to bind the dataset to the `selectAll` query, then appends a `<p>` element for each value via the `.enter()` and `.append` chain. Each new paragraph is given the static text "New paragraph!" and the animation runs in a browser. The example highlights D3’s declarative approach to data-driven document manipulation.

D3 Page Template

This example shows a minimal D3 page template that appends a new paragraph element to the body of an HTML document. The code uses the D3 selection method `d3.select("body").append("p")` to add the element, then sets its text content to "New paragraph!" via the `.text()` method. The page loads D3 from a local file and demonstrates the fundamental pattern of chaining D3 methods to manipulate the DOM. No data is involved; it is a bare-bones starting point for more complex visualizations.

07. D3 Paragraphs Style

This example demonstrates how to apply styling to HTML paragraphs created with D3’s data join. The code selects the `body` element, binds an array of five numbers to `p` elements, and appends a paragraph for each value, setting its text to “I can count up to” followed by the number. The paragraphs are then styled with red text using the `.style()` method with the property `color`. This showcases D3’s declarative approach to DOM manipulation and element styling.

06. D3 Paragraphs Counting

This example demonstrates how to bind a small array of numbers to paragraphs in the DOM, dynamically inserting text that counts up to each value. Using D3.js version 4.5.0, the code employs `d3.select`, `selectAll`, `data`, `enter`, and `append` to create new paragraphs, then applies the `text` function to render the counting sentence. The visualization is rendered entirely as HTML text elements, with no external data source.

D3.js

This example demonstrates a minimal HTML page that uses JavaScript to dynamically change the color of all paragraph elements to blue. The code retrieves paragraphs using the Document Object Model (DOM) API `document.getElementsByTagName`, iterates through them, and applies an inline CSS style property via `style.setProperty`. It relies on standard browser APIs rather than external libraries, with the script loaded asynchronously through the `defer` attribute in the HTML markup. The page contains no visual data visualization, focusing instead on basic DOM manipulation and styling.

what am I doing d3

This example demonstrates a minimal "Hello D3 version 7" message rendered directly into a paragraph element using the `select` API from D3 v7. The page loads the D3 library from a CDN and applies a large 13em font size to the body for visual impact. The code imports the `select` function and calls it on the DOM to set the text content, showing how to begin using D3’s selection and manipulation methods in a straightforward way.

Learn d3.js

This example demonstrates basic DOM manipulation with D3.js v4, showing how to select and modify elements in an HTML document. It changes the text and styling of an existing heading, applies red coloring to it, and appends three new paragraph elements to the body. The code uses `d3.select` and `d3.selectAll` to target the heading and paragraphs, then chains `.style`, `.attr`, `.text`, and `.append` methods to update content and set colors. All paragraphs are colored blue, while the heading receives a red style and a new class attribute.

HTML Starter

This example demonstrates the fundamental pattern of D3.js selection and data binding by rendering three paragraph elements inside a single div. The code uses `d3.select`, `selectAll`, and `data` to apply an array of numbers `[1, 2, 3]` to the page, then calls `enter` and `append` to create the paragraphs, with `text` formatting each element’s numeric value. It relies on the D3 v5 library loaded from a CDN, paired with a minimal `index.html` structure and a CSS file that resets margins for a clean, full-bleed display.
