This example demonstrates the general update pattern in D3, showing how SVG elements are added, removed, and modified over time. A bowl of fruit, rendered as red apples and yellow lemons, changes as a timer triggers actions: five apples appear, one is removed, an apple transforms into a lemon, and another apple is deleted. The implementation uses D3's `select`, `merge`, and `exit` operations to handle entering and exiting elements, with `scaleOrdinal` mapping fruit types to circle radii and colors.

Bowl of Fruit - General Update Pattern Special Cases

This example demonstrates the general update pattern with special cases in D3 v5, showing a bowl of fruit that changes over time: apples are eaten, removed, or replaced by lemons. It uses `d3.scaleOrdinal` for color and radius mapping, and SVG circles and text elements rendered within groups. The update flow handles entering, updating, and exiting elements via `selection.enter()`, `merge()`, and `exit().remove()`, with data-driven transforms positioning each fruit. A rectangular bowl shape persists throughout.

Bowl of Fruit - General Update Pattern Special Cases

This example demonstrates the general update pattern's special cases by showing a bowl of fruit that changes over time: apples are eaten, one apple is replaced with a lemon, and another apple is removed. Using D3 v5’s `selectAll`, `enter`, `merge`, and `exit` methods, the code updates SVG groups and shapes incrementally. Ordinal scales from `d3` map fruit types to colors and radii, while `setTimeout` triggers sequential state changes in the data array.

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.

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.

Bowl of Fruit - General Update Pattern Special Cases

This example demonstrates D3's general update pattern with special cases for entering, updating, and exiting elements. A bowl of fruit (apples and lemons) is rendered as SVG circles and text labels, with transitions over time as fruits are removed or replaced. The code uses `d3.scaleOrdinal` for color and radius mapping, `selection.merge`, and `selection.exit().remove()` to handle data joins. Fruits are imported from a module and rendered in a fixed bowl rectangle.

Bowl of Fruit - General Update Pattern Special Cases

A bowl of fruit demonstrates D3's general update pattern with special cases, showing apples and lemons as colored circles that appear, disappear, and change type over time. Using `d3.scaleOrdinal` for color and radius, the code binds fruit data to SVG `g` elements, merging entering and updating selections with `.merge()` and removing exits with `.exit().remove()`. Timed `setTimeout` calls trigger updates: removing the last apple, replacing one apple with a lemon, and filtering out a middle fruit. The example renders in an SVG container with a rounded rectangle bowl drawn via `rect` attributes.

Bowl of Fruit - General Update Pattern Special Cases

This example demonstrates the general update pattern in D3.js by animating a bowl of fruit where apples are eaten, replaced with lemons, and removed over time. Using D3 v5, the code binds an array of fruit objects to SVG groups, with enter, merge, and exit selections handling transitions for circles and text labels. It uses scaleOrdinal for color and radius mapping, and setTimeout calls trigger sequential updates every second to showcase special cases like modifying existing elements and filtering arrays.

Bowl of Fruit - General Update Pattern Special Cases

This example demonstrates special cases of the general update pattern in D3.js (v5). It shows a bowl of fruit where apples are initially added, then one is removed, another apple changes into a lemon, and finally a different apple is removed. The visualization uses SVG rendering with D3's selection, merging, and exit/remove methods to handle transitions between data states. The code uses `scaleOrdinal` for color and radius mapping based on fruit type, while data updates occur through setTimeout calls.
