Bowl of fruit - General Update Pattern

A bowl of fruit demonstrates the D3 general update pattern, showing apples and lemons rendered as colored circles that are added, removed, and changed over time. The visualization uses d3.select, data joins, and enter/merge/exit selections in the fruitBowl function, with d3.scaleOrdinal mapping fruit types to colors and radii. The SVG output updates through three timed transitions, first removing an apple, then changing an apple to a lemon, and finally filtering out another apple.

Bowl of Fruit - General Update Pattern

A bowl of fruit demonstrates D3’s general update pattern for smoothly adding, removing, and modifying SVG elements. Five apples initially appear in a rounded rectangle; over time, one apple disappears, a second is replaced by a lemon, and a third is removed. The `fruitBowl` function uses `selection.data`, `enter`, `merge`, and `exit` to bind fruit objects to groups, updating circle colors and radii via `d3.scaleOrdinal`, with text labels. D3 v7 handles the data joins, while `setTimeout` triggers re-renders.

Bowl of Fruit - General Update Pattern

This example demonstrates the D3 general update pattern by rendering a bowl of fruit as SVG circles that change over time. Using `d3.scaleOrdinal` for color and radius mapping, the `fruitBowl` function joins data to circle elements, handling enter, update, and exit selections with `.enter()`, `.merge()`, and `.exit().remove()`. Apples and lemons are distinguished by type, and timed interactions remove fruits or replace an apple with a lemon, showing how the visualization synchronizes DOM elements with changing data.

A bowl of fruit demonstrates the D3 general update pattern, showing how a visualization can add, remove, and modify data points. Five apples initially appear in a grey bowl; sequentially, an apple is removed, an apple changes into a lemon, and another apple is deleted. The code uses D3 v5 with a scaleOrdinal color and radius mapping, and employs selection merging via `.merge()` in the `fruitBowl` function to handle entering, updating, and exiting elements in the SVG.

Bowl of Fruit - General Update Pattern

Five circles represent apples in an SVG bowl, and a sequence of animated updates demonstrates D3's general update pattern. The visualization starts with five apples, then removes one, changes another into a lemon, and finally filters out a third fruit, using enter, merge, and exit selections. D3 v6 scales map fruit types to colors and radii, while transitions animate radius and position changes over one second. The `fruitBowl` module handles the data join with `selection.data`, `enter.append`, and `exit.remove` APIs.

Bowl of Fruit - General Update Pattern

An animated bowl of fruit demonstrates D3’s general update pattern, showing five fruits that disappear or change type over time. The SVG visualization uses a single reusable `fruitBowl` function, which binds data arrays to `g` groups via `selection.data()`, then handles enter, update, and exit selections with `enter().append()`, `merge()`, and `exit().remove()`. Fruit appearance relies on `scaleOrdinal` color and radius scales, while timed `setTimeout` calls trigger data mutations—removing apples or replacing one with a lemon—to illustrate smooth transitions in the rendered circles and labels.

This example demonstrates the D3 general update pattern with a bowl of fruit rendered as SVG circles. Apples and lemons are distinguished by color and radius using `scaleOrdinal`, while animated transitions adjust circle positions and sizes over one second. The code explicitly manages enter, update, and exit selections, shrinking removed fruit to zero radius via `transition.attr('r', 0)` and `.remove()`. Data mutations—deleting an apple, changing one to a lemon, and filtering another—occur at timed intervals, showing how the visualization responds to changing data through D3 v5's data join.

Bowl of Fruit - General Update Pattern

This example demonstrates the D3 general update pattern with a bowl of fruit that changes over time. An SVG renders circles representing apples and lemons, with color and size determined by `d3.scaleOrdinal` scales. The `fruitBowl` function uses `selection.selectAll`, `enter()`, `merge()`, and `exit()` to handle data joins, while `setTimeout` triggers state changes—removing fruits and replacing an apple with a lemon—to show how the visualization updates dynamically.
