This example animates a fruit bowl where apples and lemons appear, disappear, and change type while maintaining stable object identity through a general update pattern. The visualization uses D3 v6 with SVG and transition methods, assigning each fruit a unique ID and using ordinal scales for color and radius. The D3 `transition` with a 2000-millisecond duration smoothly moves circles and text to new positions as the data array changes via `pop()`, `filter()`, and type reassignment.

Object constancy

Five fruits sit in a row as colored circles with labels, shifting position when an apple is removed or changed into a lemon. The d3 selection with a key function preserves each fruit’s identity across updates, while `transition().duration()` animates the circle’s radius to zero on exit and slides the remaining fruits to their new slots. `scaleOrdinal` maps fruit type to color and radius, and all rendering uses SVG.

D3 General Update Pattern (Object Constancy)

Five apples appear in a row, then the visualization animates through data changes while maintaining object constancy by keying each circle to a stable `id`. D3’s general update pattern merges entering, updating, and exiting selections, using `transition().duration(1000)` to grow new circles from radius zero, shrink removed ones, and smoothly reposition elements. The `fruitBowl` function applies ordinal color and radius scales to distinguish apples from lemons, while `setTimeout` calls trigger pop, type-swap, and filter operations on the fruit array.

ANIMATION

This example demonstrates a dynamic fruit bowl where apples and lemons appear, disappear, and change type over time, governed by a series of timed state updates. It shows how D3's data-join pattern (enter, merge, exit) handles array mutations, with ordinal scales mapping fruit types to colors and radii. The code uses `d3.scaleOrdinal` for styling and SVG `circle` and `text` elements, while rendering is triggered by `setTimeout` callbacks that modify the data array and re-invoke the render function.

Bowl of Fruit - General Update Pattern2, object constancy

Circles representing apples and lemons transition smoothly within an SVG, demonstrating D3's general update pattern with object constancy. The visualization shows how data joins preserve element identity across updates, animating enter, update, and exit selections via `selection.merge()` and `transition().duration()`. Using React-compatible rendering, the example manipulates a fruit array with `setTimeout`, removing items or changing types, while D3 v5's `scaleOrdinal` maps fruit types to colors and radii. This highlights keyframe-less state changes through reusable D3 functions.

Bowl of Fruit: Object Constancy

Five apples appear in a row, then fade and slide in response to timed data updates that remove fruits or change an apple into a lemon, preserving each circle’s identity via a stable `id` key. The example demonstrates D3’s object constancy pattern by using `selection.data` with a key function, `enter`, `merge`, and `exit` selections, plus chained `transition` calls to animate radius and x-position over one second. Rendering uses SVG circles with d3-color scales for fill and size.

fruit bowl

This example demonstrates animated transitions of fruit in a bowl, showing apples and lemons as circles that move, resize, and disappear over time. The visualization uses D3.js scaleOrdinal functions for color and radius mapping, with a custom fruitBowl function handling the SVG circle elements via selection, enter, merge, and exit transitions. The code animates changes over a 6-second sequence, including removing an apple, changing an apple to a lemon, and filtering the fruit array.

Bowl of Fruit - General Update Pattern w/ Basic Animated Transitions

This example demonstrates the D3 general update pattern by animating a bowl of fruit represented as colored circles. Apples and lemons appear, change type, and disappear from an SVG canvas, with smooth transitions adjusting position and radius over one second. The code uses `selection.data()`, `.enter()`, `.merge()`, and `.exit()` alongside `transition().duration()` to manage object constancy based on unique IDs. The `scaleOrdinal` maps fruit types to colors and sizes.

of Fruit - Animated Transitions

Animated fruit bowl circles transition smoothly between states as apples are eaten or replaced by lemons. Using D3 v5 with SVG rendering, circles enter and exit by animating their radius from zero to its final value, while updates transition both position and size. The d3 selection join pattern with object constancy via id tracks individual fruits across data changes. Color and radius are mapped through d3.scaleOrdinal with transition durations of one second.
