Bowl of Fruit - General Update Pattern Special Cases

This example demonstrates the general update pattern in D3, showing how data joins handle adding, removing, and modifying elements. A bowl of five apples is rendered as SVG circles and text labels; one apple is eaten, another turns into a lemon, and a third is removed. The code uses `selection.selectAll`, `selection.enter`, `selection.merge`, and `selection.exit` to manage the transitions. It relies on `d3.scaleOrdinal` for color and radius mappings, and `d3.select` to target the SVG container.

This example demonstrates the general update pattern's special cases using a bowl of fruit rendered as SVG circles and text. It shows how to handle data joins when elements are removed, updated in place, or filtered out, with apples and lemons appearing and disappearing from the bowl. The code uses d3-selection’s `data`, `enter`, `merge`, and `exit` methods alongside `scaleOrdinal` for color and radius mapping, driven by `setTimeout` calls in index.js.

This example demonstrates the general update pattern with special cases, showing a bowl of fruit where apples are added, removed, and replaced by lemons over time. Using D3 v5 with SVG rendering, the code employs data joins with key functions to track fruit identities, handling enter, update, and exit selections. Ordinal scales map fruit types to colors and radii, while click events select individual fruits with a highlighted stroke. The bowl itself is a static rectangle, and the animation sequence reveals how D3’s selection.merge and exit methods manage dynamic data changes.

This example demonstrates the general update pattern in D3, showing how to handle data joins when adding, removing, and modifying elements. It uses `d3.scaleOrdinal` for color and radius mapping, with SVG circles and text rendered inside groups. The code creates five apples, then removes one, replaces one with a lemon, and filters out another, animating each change via `setTimeout` and re-rendering with `selection.merge`. The bowl is drawn as a rounded rectangle, and fruit types are color-coded through the ordinal scale.

Bowl of Fruit - General Update Pattern Special Cases

This example demonstrates the general update pattern in D3 with special cases for handling data changes. It shows a bowl of fruit rendered as SVG circles and text labels, where apples and lemons are added, removed, and modified over time. The code uses `selection.enter()`, `selection.merge()`, and `selection.exit()` to manage entering and exiting elements, with `d3.scaleOrdinal` mapping fruit types to colors and radii. A timed sequence updates the data array, triggering re-renders that add, replace, or remove fruit items.

This example demonstrates the General Update Pattern in D3 v5, showing how data joins handle special cases like adding, removing, and modifying elements. Rendered as an SVG bowl of fruit, apples and lemons are drawn as circles and text labels using scaleOrdinal for color and radius. The code shows explicit enter, update, and exit selections via groups, merging enter with update nodes, and removing exited elements. A timed sequence triggers fruit removal and type changes to illustrate the pattern’s behavior.

A bowl of fruit demonstrates the general update pattern's special cases in D3 v5, showing how data joins handle adding, removing, and modifying elements. The visualization updates five apples over time: an apple disappears, another becomes a lemon, and a third is filtered out. Using SVG, the code employs `selection.enter()`, `selection.merge()`, and `selection.exit()` to manage circles and text, with `scaleOrdinal` for color and radius mapping. The `fruitBowl` function binds fruit data to groups, updating their transforms and attributes automatically.

Bowl of Fruit - General Update Pattern Special Cases

This example demonstrates the general update pattern in D3, handling special cases when a data array changes through add, remove, and mutation operations. A row of apples rendered as SVG circles is modified over time: one apple is eaten, another becomes a lemon, and a middle apple disappears. The code uses D3’s `selectAll` with data joins, `.enter()`, `.merge()`, and `.exit()` to manage entering, updating, and exiting elements. The `fruitBowl` function uses scaleOrdinal to map fruit types to colors and radii, with circles and text labels positioned by index.
