A bowl of fruit demonstrates D3's general update pattern with special cases for enter, update, and exit selections. The code uses `d3.scaleOrdinal` to map fruit types to colors and radii, while `selection.data` with a key function tracks fruit identities across transitions. As apples are eaten, replaced with lemons, or removed, `transition.attr` animates circle radii and fill colors, with exiting elements shrinking and turning blue before removal. The example renders SVG with animated transitions in d3.v5, using `selection.merge` to handle entering and updating elements uniformly.

Bowl of Fruit - General Update Pattern

A bowl of fruit demonstrates the D3 general update pattern for enter, update, and exit selections. Apples and lemons enter as circles that scale up from radius zero, update their fill color and size through a one-second transition, and exit by shrinking away. The code uses `selection.data`, `selection.enter`, `selection.merge`, and `selection.exit` with `transition.attr` to animate SVG circles, while `scaleOrdinal` maps fruit types to colors and radii. Data changes are triggered by `setTimeout` calls that remove, replace, or filter items from the fruits array.

Bowl of Fruit - General Update Pattern Special Cases

This example demonstrates the general update pattern in D3 with special cases for entering, updating, and exiting elements. It shows a bowl of fruit where apples are added, removed, and replaced with lemons over time, with transitions animating position and opacity changes. The code uses `d3.scaleOrdinal` for color and radius mappings, `selection.merge` for combining enter and update selections, and `transition.duration` for smooth animations. The visualization renders as SVG with circles and text labels inside a rounded rectangle bowl.

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 the general update pattern in D3, showing how data joins handle enter, update, and exit selections as apples are eaten and replaced with lemons. Ordinal scales map fruit types to circle radii and fill colors, with SVG groups and circles rendered via `d3-selection`. The code uses `selection.merge()` for updates, `selection.exit().remove()` for removals, and `d3.range()` to initialize five apples, then sequentially modifies the array with `pop()`, property reassignment, and `filter()` at timed intervals.

Bowl of Fruit - General Update Pattern Special Cases

This example demonstrates the general update pattern in D3.js with special cases for entering, updating, and exiting data. It shows a bowl of fruit where apples are added, eaten, replaced by lemons, and filtered out over time, using animated transitions. The code uses D3 v5’s `selection.enter`, `selection.merge`, `selection.exit`, and `transition.duration` to handle these updates, with ordinal scales for color, radius, and font size. Rendering occurs in an SVG via `circle` and `text` elements.

Bowl of Fruit - General Update Pattern Special Cases

A bowl of fruit demonstrates special cases in the General Update Pattern with d3.v5, showing how SVG elements animate as apples are added, eaten, and replaced by lemons. Circles and text labels transition in and out over one second, with radius and color scales mapping fruit types. The example uses explicit `selection.selectAll`, `.enter()`, `.merge()`, and `.exit().transition()` calls to handle data-driven updates.

Bowl of Fruit — General Update Pattern + Transitions

A bowl of fruit animates through the D3 general update pattern, demonstrating enter, update, and exit selections with smooth transitions. Apples and lemons appear as colored circles, scaling radius and shifting horizontally as items are added, removed, or change type over time. The example uses d3-selection's `selectAll`, `data`, `merge`, and `exit` methods, along with `transition().duration()` to animate SVG circle attributes. A color scale and radius scale map fruit types to visual properties, while randomly generated IDs track elements across updates.

Bowl of Fruit - General Update Pattern

This example demonstrates the D3 general update pattern by animating a bowl of fruit, where circles representing apples and lemons appear, disappear, and change color through data-driven transitions. It shows enter, update, and exit selections working together as fruits are eaten or replaced over time. The code uses `selection.data()` with a key function, `selection.enter()`, `selection.merge()`, and `selection.exit()` alongside `transition()` for smooth radius and position changes. D3’s `scaleOrdinal` maps fruit types to colors and radii, while `Math.random()` generates unique IDs for each fruit.
