Bowl of Fruit - General Update Pattern

Bowl of Fruit - General Update Pattern

A bowl of fruit demonstrates D3’s general update pattern for animated data joins. Circles represent apples and lemons, colored via a `scaleOrdinal` and sized by another. Each update transitions entering, updating, and exiting circles using `transition().duration(1000)`, shrinking exits to zero radius before removal. The example cycles through adding, removing, and mutating fruit types with `setTimeout`, showing how D3’s `selection.data` with a key function manages dynamic datasets. Rendering uses SVG in a static 960×500 viewport.

This example demonstrates the D3 general update pattern with a bowl of fruit animation. It shows how data joins handle entering, updating, and exiting elements: apples disappear, one apple transforms into a lemon, and fruit positions shift accordingly. The code uses `selection.data()`, `selection.enter()`, `selection.exit()`, and `selection.merge()` within a custom `fruitBowl` function, animating circle radii via `transition().duration(1000)`. Fruits are generated with `d3.range` and `Math.random()` IDs, rendered as SVG circles and text elements with a `scaleOrdinal` color scale.

This example demonstrates the general update pattern in D3, showing how data joins handle entering, updating, and exiting elements with smooth transitions. Circles represent fruits and are color-coded by type using `scaleOrdinal` for both color and radius. The `fruitBowl` function uses `selection.data`, `.enter()`, `.merge()`, and `.exit()` with `transition().duration()` to animate new apples fading in and removed fruits shrinking away. A series of `setTimeout` calls manipulates the fruit array, popping an apple, changing one to a lemon, and filtering another, all rendered as SVG.

Bowl of Fruit - General Update Pattern

A bowl of fruit demonstrates the general update pattern for handling data changes in D3. Circles representing apples and lemons enter, update, and exit with animated transitions, while hovering highlights the selected fruit. The code imports `scaleOrdinal` from d3, uses `selection.data`, `.enter()`, `.merge()`, and `.exit()`, and renders SVG circles with `transition().duration()`. Data is defined in `index.js`, with timed operations removing items and changing an apple to a lemon.

Bowl of fruit General Update Pattern

A bowl of fruit demonstrates the D3 general update pattern with animated enter, update, and exit transitions for circles. Apples and lemons render as colored SVG circles using ordinal color and radius scales, with positions determined by index. The code uses `selection.data`, `enter`, `merge`, and `exit` methods alongside `transition().duration()` to smoothly resize and reposition elements as fruits are removed and types changed over timed intervals.

Bowl of Fruit - General Update Pattern

A bowl of fruit demonstrates D3's general update pattern, showing how data joins handle entering, updating, and exiting circles. Apples and lemons appear as colored circles that animate radius and position when fruits are eaten or replaced. The example uses `d3.scaleOrdinal` for color and radius scales, while `selection.data`, `enter`, `merge`, and `exit` chains manage transitions with `transition.attr` over one-second durations. Random IDs track stable elements across updates, and the SVG renders in a 960×500 viewport driven by timed `setTimeout` state changes.

Five circles representing apples shrink away and are replaced as a lemon appears, demonstrating D3's general update pattern through enter, update, and exit selections. The example uses `scaleOrdinal` for fruit type colors and radii, with `transition().duration(1000)` animating circle resizing and removal. Data flows through `data(fruits, d => d.id)` keyed by random IDs, while the `fruitBowl` function manages the merge and exit transitions.

A bowl of fruit demonstrates D3's general update pattern, showing apples as dark red circles and lemons as yellow ones with distinct radii. New fruit enter at radius zero and grow, existing fruit move horizontally and change fill when types change, and removed fruit shrink away. The example uses D3 v5 selections with `.data()`, `.enter()`, `.merge()`, and `.exit()`, applying transitions over one second to animate SVG circle attributes. A simple timeline triggers updates by popping apples, replacing one with a lemon, and filtering out another.
