This example demonstrates D3.js (v4) enter(), update(), and exit() transitions for animated data visualization. A button click toggles between two predefined numeric arrays, and the SVG scene displays a horizontal axis line with a text label above it. Using the data join and the merge() method, circles are smoothly animated to new positions and radii, while exiting circles shrink to zero radius before removal. The code leverages D3's selection, transition, and duration APIs on SVG elements, with a stylesheet defining visual properties like fill, stroke, and opacity.

d3js - enter(), update() and exit()

A bar of five orange circles sits along a horizontal axis, with a button to swap between two data arrays of different lengths. Using D3 v3, the example demonstrates the data-join pattern: `enter()` appends new circle elements when longer data arrives, `exit()` removes surplus circles when data shrinks, and a `.transition()` updates all remaining circles’ radii and positions. The axis is drawn as simple SVG `line` elements with `text` labels, and the dataset label updates with each toggle.

D3.js - join() with enter, update, and exit

This example demonstrates D3.js’s `join()` method by binding an array of numbers to SVG circles, with buttons to prepend, append, or drop data items. Entering circles animate their radius from zero and color to hotpink via `transition.attr`, while updated circles shift horizontally and exiting circles shrink to zero before removal. The code uses a key function `(d) => d` for datum identity, `d3.selectAll`, `.data()`, and `.join()` with separate enter, update, and exit handling. Rendering uses SVG and transitions with 500-millisecond durations.

Enter, Exit, Update

This example demonstrates the enter, update, and exit phases of D3’s data-join process using three selectable buttons that swap between different arrays of named values. Each array’s items are rendered as circles, showing how new items appear, existing items change position, and removed items shrink away. The visualization uses D3 v4’s `.data()`, `.enter()`, `.exit()`, and `.merge()` methods alongside the `.transition()` API for smooth animations. The SVG circle’s fill color is mapped to each item’s `id`, while the x-coordinate is derived from its index in the current array.

D3 - Transitions

This example demonstrates three ways D3.js handles data updates with transitions. The top SVG updates circles without animation, the middle uses a simple transition to move circles smoothly, and the bottom shows an enter-update-exit pattern where new circles fade in, existing circles move, and removed circles fall downward and disappear. A button click regenerates random data values. The code uses D3 v7 selections, the `.join()` method, and `.transition()` with a duration of 1000ms, all rendered as SVG circles with fill opacity.

Fork of Template Enter, exit and update

This example demonstrates the D3.js enter, update, and exit pattern using animated SVG circles. Six circles initially appear, then one is removed after two seconds, and the first circle changes color after four seconds, with each state change triggering a two-second transition. The visualization uses `d3.select`, `d3.range`, `d3.scaleOrdinal`, and `transition()` to illustrate how data joins and lifecycle methods handle dynamic updates. The color scale maps object types to fill colors, though the initial and updated object types are not explicitly defined in the code.

D3 Transitions

Six colored circles enter, update, and exit the screen using animated D3 transitions. The initial enter animation scales each circle from a radius of zero to its target size with a staggered delay, while the update transition moves circles to new positions quickly and the exit transition shrinks them back to nothing before removal. The example demonstrates the `selection.join()` pattern with separate enter, update, and exit handlers, using `transition().duration()` and `easeLinear` from D3 v7 to control timing and motion on an SVG canvas.

D3.js - data(), join(), transition(), duration(), and key functions

Interactive buttons append, prepend, or drop numbers from an array, updating a row of animated SVG circles. The D3.js v7 code demonstrates selection joins with `data()`, `join()`, and a key function, showing how element insertion and removal works during transitions. Each click triggers a 500ms animated update via `transition().duration()`, repositioning circles horizontally while their radii scale with the numeric values.

Exit, Update, Enter

Three divs demonstrate D3's enter-update-exit pattern with staggered transitions. An existing "update" and "exit" element bind to new data, turning the update orange while the exit fades red and removes itself. A new "enter" element fades in green after a delay. The example uses D3 v3's `selection.data`, `transition.delay`, and `style` to chain animations, with explicit delay calculations based on whether exit and enter selections are empty.
