06. D3 Paragraphs Counting

05. D3 Paragraphs Text

This example demonstrates how to bind an array of numbers to paragraph elements and display each value as text content. The code uses D3’s selection methods `selectAll`, `data`, `enter`, and `append` to create `<p>` elements for each data point, then sets their text with the `text` function. The dataset `[5, 15, 20, 25]` is hardcoded, and the visualization relies on D3’s data-join pattern to render static, non-animated output.

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.

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.

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.

This example demonstrates the fundamental data-join pattern in D3.js v4, binding an array of five numbers to paragraph elements. It displays the numbers 1 through 5 as text content in separate paragraphs on an HTML page. The code uses `d3.select`, `selectAll`, `data`, `enter`, and `append` to create the elements, with a callback function in `.text()` to set each paragraph’s content from the dataset. The visualization relies on the D3.js v4 library, loaded from a CDN, and runs within a minimal HTML structure.

08. D3 Paragraphs Style Function

This example demonstrates how D3.js can set paragraph styles conditionally based on data values. It selects the body element and appends a paragraph for each number in the dataset [5, 10, 15, 20, 25], with text displaying the count. Using the `.style()` method, paragraphs with data values greater than 10 are colored red, while others remain black, illustrating data-driven styling with D3’s selection and data-binding APIs.

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.
