Bowl of Fruit - General Update Pattern Special Cases

Bowl of Fruit - General Update Pattern Special Cases

This example demonstrates the general update pattern in D3, focusing on special cases when data elements are added and removed. As apples are bought and eaten, the visualization animates new fruit entering the bowl while existing fruit exits, with circles and text labels scaling down before removal. The bowl itself resizes to accommodate the changing number of fruits. The code uses D3 v5 APIs including `selection.selectAll`, `.enter()`, `.merge()`, `.exit()`, and transitions with `.duration()`. It renders to SVG with ordinal scales mapping fruit types to colors and radii, with a timeout delaying the bowl’s width adjustment.

Bowl of Fruit - General Update Pattern Special Cases

This example demonstrates D3.js's general update pattern and its special cases using a bowl of fruit metaphor. A static bowl initially displays five apples, but the code includes commented-out scenarios for removing, replacing, and filtering fruits to illustrate update transitions. The visualization uses `d3.scaleOrdinal` for color and radius mapping, and `selection.merge` to handle enter, update, and exit states for SVG circles and text elements. The rendering is driven by the `fruitBowl` function and triggered through `select` and `range` APIs from D3 v5.

Bowl of Fruit - General Update Pattern Special Cases

This example demonstrates the general update pattern in D3 v5, showing how to handle enter, update, and exit selections for a simple bowl of fruit visualization. A row of apples is displayed as circles and text, with fruits being removed, replaced, and filtered over time using `setTimeout`. The code uses `selection.data()`, `selection.enter()`, `selection.merge()`, and `selection.exit()` to manage SVG groups, while `scaleOrdinal` maps fruit types to colors and radii. The rendering approach is SVG-based, with the fruit positions computed via `translate` transformations inside the `fruitBowl` function.

Bowl of Fruit - General Update Pattern Special Cases

This example demonstrates the general update pattern in D3, showing how SVG groups representing fruit are added, removed, and modified. The bowl shape is drawn as a static rectangle, while a dynamic array of apples and lemons is bound to `g` elements using `selection.data`. The code uses `selection.enter`, `selection.merge`, and `selection.exit` to handle entering, updating, and exiting fruits, with circles sized and colored via `d3.scaleOrdinal`. Data is initially five apples, then changes through `pop` and array filtering, rendering via a custom `fruitBowl` function.
