This example demonstrates how D3’s enter and update selections behave when binding an array of five numbers to existing and empty paragraph groups. Three sections show different styling strategies: the first inserts all paragraphs as green enter selections, the second merges enter and update selections before applying violet text and color, and the third styles update selections blue and enter selections green separately before setting text. The code uses `d3.select`, `.data()`, `.enter().append()`, and selection merging via `sec2_update`. Data is hardcoded as `[1,2,3,4,5]`, and the script runs after a two-second delay via `setTimeout`.

D3 selections

This example demonstrates D3’s selection and data-join mechanism. It maps an array of five numbers to paragraph elements, appending each value as text. Paragraphs whose data values exceed 15 are then filtered and styled with red, bold text using D3's `.filter()` method. The code uses `d3.select`, `.selectAll`, `.data`, `.enter()`, and `.append()` to bind the array and create the DOM nodes, with styling applied via `.style()`.

simpleEnterExitUpdate

This example demonstrates how D3’s data join handles enter, update, and exit selections in a simple HTML div chart. It starts with three static divs (Billy, Cindy, Walter) and binds them to a new array of five score objects using a key function that matches by name. The existing divs turn red as the update selection, while Alice, David, and Emily are appended in green via `update.enter()`; the exit selection removes any unmatched elements. The code uses `d3.select`, `selectAll`, and `data` with a custom key function, and applies styles directly via `.style()` rather than SVG or canvas rendering.

d3 update() enter() exit()

This example demonstrates how D3’s data join updates existing DOM elements and adds new ones. The page initially contains three `<p>` elements for dog, cat, and pig. The code binds an array of five numbers to these paragraphs using `d3.select` and `selectAll`, then calls `data()` to get the update set. Using `update.text()`, it rewrites the existing paragraphs with their new values and indices. The `update.enter()` method appends two new `<p>` elements, each filled with the remaining data values via `append` and `text`. The example showcases D3’s declarative enter/update/exit pattern for syncing data to HTML.

enterExitUpdate

This example demonstrates how the D3.js v4 `select` API and its associated enter, update, and exit methods manage dynamic data changes. A small bar chart, initially displaying three names (Billy, Cindy, Walter), is updated with a hard-coded array of five scores. The update selection re-colors existing elements red, the enter selection inserts new divs for Alice, David, and Emily in green, and the exit selection removes stale elements. Both update and enter selections are merged and styled to display each score as a proportional bar width. The code relies on `d3.select`, `.data()`, `.enter()`, `.exit()`, and `.merge()`.

8. update-enter-merge-exit

This example visualizes the D3 general update pattern, showing how a data-join with enter, update, and exit selections manages a changing set of letters. Entering elements appear in green, updating elements in black, and exiting elements are removed immediately. The code uses `d3.shuffle` and `slice` to generate random subsets of the alphabet every second, and `d3.interval` to trigger a custom `update` function. Without a key function, enter elements append at the end and exit elements remove from the end, demonstrating positional data binding in SVG.

SelectionTinker

Two HTML paragraphs initially render in black, then d3.selectAll changes every paragraph’s text color to blue, and finally d3.select overrides the first paragraph to red, demonstrating selection and chained styling. Using D3 v4, the example shows how a broad selection affects all matched elements while a narrower select targets only the first, with no data binding or interaction. The code relies solely on d3.select, d3.selectAll, and .style for DOM manipulation.

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.

General Update Pattern, I

This example illustrates D3’s general update pattern, where a data-join is followed by operations on the enter, update, and exit selections. Entering letters appear green, updating letters black, and exiting letters are removed immediately. Using d3-selection and d3.interval, it randomly slices the alphabet and re-sorts it every 1.5 seconds, showing how elements may change their associated letter without a key function. The SVG text elements are joined with the data, and the enter selection merges with the update selection before applying text and positioning attributes.
