This example demonstrates a data join and transition animation in D3 v5, where a set of circles representing fruits is dynamically updated. The visualization shows how the `selectAll` and `data` (with a custom key function) methods manage entering, updating, and exiting elements—new apples grow from a radius of zero, a lemon changes color and size, and a removed fruit shrinks away. The code uses D3's `scaleOrdinal` for color and radius mappings and leverages the `transition` API for smooth, 1000-millisecond animations.

Data join and Transition

This example demonstrates the data join pattern with animated transitions in D3 v5, showing how circles representing fruit enter, update, and exit. Starting with five apples, the visualization removes a fruit after one second, changes the third fruit's type to lemon at two seconds, and filters out another item at three seconds. Each change triggers a smooth 1-second transition where new circles grow from radius zero, existing circles adjust their color, size, and position, and removed circles shrink away. The code uses `selection.data()`, `selection.enter()`, `selection.merge()`, and `selection.exit()` with `transition().duration()` for the animations, along with `scaleOrdinal` for color and radius mapping.

D3 data join

This example demonstrates D3’s data join pattern by animating a bowl of fruit rendered as SVG circles. It shows how entering, updating, and exiting elements are handled when the underlying data array changes over time. The code uses `selection.data`, `enter`, `merge`, and `exit` with `transition` to smoothly resize and reposition circles, while a scale maps fruit types to colors and radii. The dataset is generated in JavaScript with random IDs, and three timed updates modify the array to trigger the join animations.

Intro to Transitions

Five circles representing fruit transition smoothly as they are added, updated, and removed. The example demonstrates D3's data join with enter, update, and exit selections. Using d3.transition with a one-second duration, each circle's radius, fill color, and x-position animate via attribute interpolation. The code uses scaleOrdinal for categorical color and radius mapping, and random IDs to track elements as apples are replaced by lemons and removed over timed intervals.

Rendering a fruit bowl as animated SVG circles and labels, this example demonstrates how D3's data join and exit selections handle dynamic updates. Five apples appear, then one is removed, another turns into a lemon, and a different fruit disappears, with all transitions driven by `transition().duration()` over 1000 milliseconds. The code uses `d3.scaleOrdinal` for color and radius mapping, while mouseover and mouseout events update a selected fruit's stroke outline. Data mutations trigger `render()` calls, which rebuild the visualization from the current array state.

About fruits

This example shows how a data join animates changes to a fruit bowl. Five apples are initially rendered as circles, then one is removed, another transforms into a lemon, and a third is eaten, all with smooth transitions. Using D3's `select`, `range`, and `scaleOrdinal`, the `fruitBowl` function manages circle enter, update, and exit states via `.transition().duration(1000)`, animating radius and position. The SVG output is updated dynamically as JavaScript timeouts trigger the re-rendering.

animated transitions try

The example demonstrates animated transitions of fruit shapes in an SVG bowl, showing apples and lemons that appear, disappear, and change type over time. Using D3.js v5 with the `select`, `range`, and `scaleOrdinal` APIs, it employs data joins with enter, update, and exit selections. The `fruitBowl` module handles rendering, applying `transition().duration(1000)` to smoothly animate circle radii and colors as fruits are eaten or replaced.

Animations

Animated fruit bowl demonstrations show how data joins and transitions work in D3.js, with apples and lemons appearing, disappearing, and changing type over time. Using `selectAll` and the `.enter()`, `.merge()`, and `.exit()` selection APIs, circles animate their radius and position through `.transition()`. A separate face graphic uses `arc()` paths and tweened eyebrow movements, while click and hover interactions trigger selection states that update stroke styling.

Fruitbowl V2 transitions

Rows of apples and lemons animate as fruit is eaten or replaced in this SVG chart. The example demonstrates D3's data join with a key function, using `selection.enter`, `merge`, and `exit` to manage updates. Transitions smoothly shift circle positions and radii over one second. Data arrays are modified via `setTimeout`, triggering re-renders with `d3.scaleOrdinal` mapping fruit types to colors and sizes.
