This example demonstrates enter, exit, and update transitions in D3 by animating fruit objects represented as SVG circles. Initially, five apples appear; after four seconds, the rightmost apple exits by shrinking and disappearing, while another apple is replaced by a lemon (update). A subsequent removal filters out the second apple, triggering an exit transition. The code uses `d3.select`, `d3.scaleOrdinal`, and D3's transition API with `.transition().duration()`, `merge()`, and `.exit()` to handle the changes smoothly over six seconds.

D3-7: Enter, Exit, Update

This example demonstrates D3’s enter, exit, and update pattern with a fruit-themed dataset. Five apples render as red circles in a rounded steelblue bowl; after two seconds, one apple is removed, and after four more, the third apple becomes a lemon, changing its size and color. The `rend` function uses `selectAll`, `data`, and `.enter().append()` to create circles and text, `.merge()` to update attributes via `transition().duration(1000)`, and `.exit().remove()` to delete elements. It relies on `scaleOrdinal` for color and radius mappings, with two `setTimeout` calls triggering updates.

Transition exercise

A sequence of five apples renders in an SVG. Over three seconds, scheduled changes transform the data: one apple is eaten, a second apple becomes a lemon, and another apple is removed. Each update re-renders the scene, with D3's `select`, `merge`, and `exit` APIs animating the SVG elements to their new positions and styles. The fruitbowl module uses `scaleOrdinal` for color and radius scales, and the example demonstrates D3’s declarative transition system for entering, updating, and exiting marks.

d3 enter/update/exit patterns

This example demonstrates the classic D3 enter/update/exit pattern for animating changes to a dataset. Over a timed sequence, fruits are removed, a lemon replaces an apple, and another item is filtered out, all while the visualization smoothly transitions the circles' positions and radii. The code uses D3's selection `merge` and `.transition().duration()` methods to animate attribute changes, with `circles.exit()` shrinking departing elements to a radius of zero before removing them. The scene is rendered as SVG with a static bowl rect, and data is generated randomly with a color scale mapping fruit types.

A simple animated fruit bowl demonstrates D3 transitions as apples and lemons enter, update, and exit. Rendered as SVG circles, the visualization uses d3.scaleOrdinal to map fruit types to fill colors and radii. A timer triggers events that remove fruits, change an apple to a lemon, and filter the data, with each change animating over one second via the .transition() API, shrinking exiting circles to zero radius.

This example demonstrates how to update a data-bound visualization with D3’s enter, update, and exit selections. An animated fruit bowl shows apples and lemons as colored circles that appear, change type, and disappear over timed intervals. The code uses `d3.scaleOrdinal` for color and radius mapping, `selection.merge`, and `transition` to smoothly animate circle attributes. Fruit data is generated randomly with each item assigned a unique `id` to track changes across renders. All rendering is done in SVG.

Intro to Transitions

Five circles representing fruit transition smoothly as they are added, updated, and removed. The example demonstrates D3's data join with enter, update, and exit selections. Using d3.transition with a one-second duration, each circle's radius, fill color, and x-position animate via attribute interpolation. The code uses scaleOrdinal for categorical color and radius mapping, and random IDs to track elements as apples are replaced by lemons and removed over timed intervals.

Data join and Transition

This example demonstrates the data join pattern with animated transitions in D3 v5, showing how circles representing fruit enter, update, and exit. Starting with five apples, the visualization removes a fruit after one second, changes the third fruit's type to lemon at two seconds, and filters out another item at three seconds. Each change triggers a smooth 1-second transition where new circles grow from radius zero, existing circles adjust their color, size, and position, and removed circles shrink away. The code uses `selection.data()`, `selection.enter()`, `selection.merge()`, and `selection.exit()` with `transition().duration()` for the animations, along with `scaleOrdinal` for color and radius mapping.

Bowl of Fruit - General Update Pattern Special Cases

This example demonstrates the general update pattern in D3, showing how enter, update, and exit selections handle dynamic data changes in a fruit bowl visualization. Five apples appear initially, then an apple is removed, another transforms into a lemon, and a second apple disappears, with each change animating smoothly over one second. The code uses d3.scaleOrdinal for color and radius scales based on fruit type, while d3-transition animates circle radius and fill attributes. SVG groups and shapes are bound to data with unique IDs, and the enter/merge/exit pattern manages the lifecycle.
