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.

Bowl of Fruit - General Update Pattern Special Cases

This example demonstrates the D3 general update pattern through a bowl of fruit, showing how data joins handle enter, update, and exit selections over time. As apples are eaten or replaced by lemons at timed intervals, the visualization updates the SVG circles and text labels accordingly. The code uses d3.select, data binding via selection.data(), merge(), and selection.exit().remove() from D3 v5, with scaleOrdinal for color and radius mapping. Each fruit is rendered as a circle with a text label, positioned inside a rounded rect bowl.

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 data. A bowl of fruit is rendered as SVG circles with labels, starting with five apples that are then removed, replaced with a lemon, or filtered out over time. The code uses d3.scaleOrdinal for color and radius mapping, along with selection.merge and selection.exit to handle dynamic data changes. The visualization shows how data joins manage transitions between states without animation, using explicit enter and exit logic.

Bowl of Fruit - General Update Pattern

This example demonstrates the general update pattern in D3, where data changes are reflected in a bowl of fruit rendered as SVG circles. It shows how enter, update, and exit selections manage the visualization across a timeline: initially six apples appear, then one is removed, another changes to a lemon, and a fourth is filtered out. The code uses `d3.scaleOrdinal` for color and radius mapping, with `selection.merge` and `selection.exit().remove()` to handle dynamic updates.

Bowl of Fruit - General Update Pattern Special Cases

A bowl of fruit demonstrates D3's general update pattern with special cases, showing how data joins handle enter, update, and exit selections for apples and lemons. D3 v5's selection methods—`merge`, `exit().remove()`, and nested selections—manage circle and text elements across four timed transitions: adding apples, removing one, replacing an apple with a lemon, and filtering a specific index. The code uses `scaleOrdinal` for color and radius mapping, rendering SVG shapes within a static bowl rectangle, with each state change triggered by `setTimeout`.

Bowl of Fruit - General Update Pattern Special Cases

This example demonstrates the general update pattern in D3.js through a bowl of fruit visual, showing how data joins handle enter, update, and exit states. As apples are eaten and replaced with lemons over time, the code uses `selection.enter()`, `selection.merge()`, and `selection.exit()` to manage circles and text elements, with d3.scaleOrdinal mapping fruit types to colors and radii. The visualization employs SVG shapes and animations triggered by `setTimeout`, highlighting special cases where exit transitions shrink elements to zero size before removal.
