D3 Starter - General update pattern Nest

This example demonstrates the D3 general update pattern for data-bound SVG elements, using a fruit bowl metaphor to show how enter, update, and exit selections handle changing data. The code uses `d3.scaleOrdinal` to map fruit types (`apple`, `lemon`) to colors and radii, with each fruit’s position derived from its index. Over timed intervals, `setTimeout` triggers removal of apples, mutation of one apple to a lemon, and filtering of another fruit, while the `fruitBowl` function merges `enter` and `update` selections and applies transitions to exit circles. Rendering is SVG-based, with text labels showing fruit types.

D3 Starter - General update pattern Modular way

This example demonstrates the D3 general update pattern in a modular way, using animated fruit bowls to illustrate how data changes drive SVG circle and text elements. The code defines a reusable `fruitBowl` function that handles enter, update, and exit transitions for circles and labels, with `transition().duration(1500)` animating position, radius, fill color, and opacity changes. Using d3.v6's `scaleOrdinal` for color and radius mapping, the visualization cycles through adding, removing, and modifying fruit data points via `setTimeout` calls.

D3 Starter - General update pattern Nest grouped version w/transition

This example demonstrates the D3 general update pattern with nested groups, animating a fruit bowl where apples are eaten or replaced by lemons over time. The visualization uses d3.selectAll and data joins to bind fruit objects to SVG group elements, with transitions on circle radii and positions. The code leverages d3.scaleOrdinal for color and size mapping, while enter, merge, and exit selections handle dynamic updates. The animation sequence includes removing apples, changing a fruit type, and filtering the dataset.

Bowl of Fruit - General Update Pattern

This example demonstrates the general update pattern in D3.js, animating a bowl of fruit rendered as SVG circles and text labels. The visualization shows how data joins handle entering, updating, and exiting elements: five apples initially appear, then one is eaten, another transforms into a lemon, and a third disappears. Using `selection.data()` with a key function, `.enter()`, `.merge()`, and `.exit()` transitions, circles smoothly shrink, change color via `scaleOrdinal`, and reposition over one-second durations. The React framework wraps the D3 v6 code, with `d3.select` and `range` driving the state changes.

D3 General Update Pattern (Singular Elements)

This example demonstrates the D3 general update pattern with singular SVG elements by animating a fruit bowl's contents. It uses `d3.select`, `d3.range`, and `d3.scaleOrdinal` to manage a dynamic dataset of apples and lemons. The visualization sequentially removes, replaces, and filters fruit items in the bowl, showing how `selection.selectAll`, `.enter()`, `.merge()`, and `.exit()` handle transitions for the appended circles, text labels, and the background rectangle. The code explicitly shows data-driven updates through timeouts in `index.js`.

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 general update pattern in D3 with special cases for enter, update, and exit transitions. A bowl of fruit is rendered as SVG circles and text labels, with apples and lemons distinguished by color and radius using `scaleOrdinal`. Users click to double the data values, triggering the update logic that repositions all text elements via `.attr("x", ...)` and `.text()`. The visualization uses d3.select, d3.selectAll, and `.merge()` to handle overlapping enter and update selections, while `.exit().remove()` clears obsolete elements, showcasing the data join and lifecycle management.

D3 Starter - General update pattern

Five fruit circles render as apples in an SVG created with D3 v6. A function called `render` demonstrates the general update pattern by joining data to circles with `selectAll` and `data`, then handling enter, update, and exit selections. The code uses `scaleOrdinal` for color and radius based on fruit type, and `merge` to apply shared attributes. After one second, a fruit is removed; after two, an apple becomes a lemon, showing transitioned states.
