Bowl of Fruit - General Update Pattern Special Cases

A bowl of fruit demonstrates D3's general update pattern with special cases for adding, removing, and mutating data. Apples and lemons are rendered as SVG circles with color and radius scales. The code uses `selection.merge` to handle enter and update selections, `selection.exit` for removal, and joins arrays of fruit objects to `g` elements. A timer sequence pops an apple, changes one apple to a lemon, and filters out another apple to show dynamic transitions.

Bowl of Fruit - General Update Pattern Special Cases

This example demonstrates the D3 general update pattern through a bowl of fruit, where apples and lemons are added, removed, or changed over time to show how enter, update, and exit selections handle data changes. The visualization uses d3.scaleOrdinal for color and radius mapping, with SVG circles and text elements positioned in a fixed bowl shape. The code explicitly uses selection.merge, selection.exit().remove(), and setTimeout to sequence transformations, illustrating special cases like filtering out an item or mutating a datum’s type property while preserving existing DOM nodes.

Bowl of Fruit - General Update Pattern Special Cases

This example demonstrates the general update pattern in D3 with special cases for enter, update, and exit selections. It shows a bowl of fruit where apples are added, removed, and replaced with lemons over time using `setTimeout` calls. The visualization renders SVG circles and text labels for each fruit, with colors and radii mapped via `scaleOrdinal`. The code uses D3 v5 selections, `.merge()` for combining enter and update groups, `.exit().remove()` for deletions, and dynamic data binding to track state changes across transitions.
