Forked from Let's make a face with D3.js

Five fruit circles enter and animate from a zero radius, then exit and re-enter as their data array mutates over timed intervals, demonstrating the general update pattern. The React-wrapped example uses d3 v5’s `selection.data` with key functions, `transition().duration()`, and `merge()` to handle enter, update, and exit sets. Ordinal scales map fruit types to colors and radii, with SVG rendering driven by d3.select and attribute tweens.

General Update Pattern

Fruit shapes move across an SVG as the underlying data array changes, demonstrating the D3 general update pattern with enter, update, and exit selections. The code uses `d3.scaleOrdinal` to map fruit types to colors and radii, while `transition().duration(1000)` animates positional and size changes. Timed mutations—removing fruits, shifting types, and dropping the first item—trigger re-renders through a `fruitBowl` function. D3 v5 and React manage the data flow, with `d3.select` handling SVG circle elements and key-based data joining for stable identity tracking.

General Update Pattern

This example demonstrates the D3 general update pattern for data joins, where circles representing fruit enter, update, and exit with animated transitions. Fruits are drawn as SVG circles sized and colored by type via `d3.scaleOrdinal`, with positions calculated from array indices. The code uses `selection.data`, `selection.enter`, `selection.merge`, and `selection.exit` to handle updates, paired with `transition.attr` methods over one-second durations. A sequence of `setTimeout` calls modifies the fruit array by removing, changing, and splicing elements, showing how the visualization responds to data changes.

General Update pattern

This example demonstrates the general update pattern in D3.js, showing how data joins handle enter, update, and exit selections. A row of fruit circles—apples and a bitter lemon—change over time as items are removed or modified, with each circle’s fill and radius determined by a `scaleOrdinal`. The React-like component `fruitBowl` uses `selection.selectAll()` and `.merge()` to update SVG circles and text on each render, triggered by `setTimeout` callbacks. Transitions are commented out, so updates apply instantly without animation.

General Update Pattern1

This example demonstrates the D3 general update pattern, showing how data joins handle entering, updating, and exiting circles. Five fruit circles animate through transitions: apples disappear, one becomes a lemon, and new fruits are added over time. The code uses `selection.selectAll`, `.data()` with a key function, `.enter()`, `.merge()`, and `.exit()` combined with `transition().duration()` to animate radius and position changes. Scales include `scaleOrdinal` for color and radius mapping, rendered as SVG with a gradient background.

General update pattern

The example demonstrates the D3 general update pattern, animating a row of fruit circles as apples are added, removed, and replaced with lemons over time. It uses d3.select and d3.range to manage data, and the fruitBowl module applies enter, merge, and exit selections with transition.attr to animate circle radius and fill color. Rendering occurs in SVG via a React-free vanilla JavaScript setup, with d3.scaleOrdinal mapping fruit types to colors and sizes. The data consists of a mutable array of fruit objects, each with a random id for keying.

General Update Pattern

This example demonstrates the D3 general update pattern with React, using a row of fruit shapes that change over time. It shows how data joins handle enter, update, and exit selections as apples are eaten and replaced by lemons. The code uses `selection.data()` with a key function, `.enter()`, `.merge()`, and `.exit()` to manage SVG groups, circles, and text elements. D3’s `scaleOrdinal` maps fruit types to colors and radii, while `setTimeout` triggers state changes to the fruit array.

General Update Pattern-With Transitions

Five fruit circles appear in a row, then animate through removal and type changes over time. The visualization demonstrates the general update pattern with smooth transitions for entering, updating, and exiting SVG elements. It uses d3.scaleOrdinal for color and radius mapping, and d3-transition's `.transition().duration()` to animate circle radius, position, and removal. The code is built with React, d3 v5, and renders to SVG.

General Update Pattern

This example demonstrates D3’s general update pattern for smoothly transitioning a fruit bowl’s contents over time. The React-rendered SVG shows apples and lemons as colored circles, with entries scaling up from radius 0, updates shifting positions and recoloring, and exits shrinking away. Using `d3.scaleOrdinal` for color and radius, the code leverages `selection.enter()`, `merge()`, and `exit()` with `transition().duration(1000)` to animate state changes triggered by timed `setTimeout` calls that remove, replace, and filter fruit data.
