Five fruit circles enter as apples and animate through a join sequence using D3’s data-join, `enter`, `merge`, and `exit` selections. The code drives transitions for radius, color, and removal, with `d3.scaleOrdinal` mapping fruit type to size and hue. A timer updates the array, replacing an apple with a lemon and filtering out elements.

Fruit - Update Pattern - Nested

Five fruit icons animate through a sequence of data changes, demonstrating D3's nested update pattern. The visualization shows apples and lemons repositioning, changing color and radius, and being removed from the group over timed intervals. Using d3.scaleOrdinal for color and size mapping, the code applies transitions to enter, update, and exit selections. The example relies on selection.merge, transition.duration, and group elements to synchronize circles with their text labels.

Fruit - Update Pattern - Nested

Five fruit bowls render as SVG circles and labels, using an update pattern to animate changes to the data array. The example cycles through eating apples and replacing one apple with a lemon, with transitions on position, fill color, radius, and text. The code uses D3 v5 selections with enter, merge, and exit, applying `transition().duration()` for staggered animations. Fruits are generated randomly, and nested selection patterns handle updates to circles and text elements within each group.

Fruit - Update Pattern - Nested

An animated SVG demonstrates a nested update pattern for fruit data, showing an array of apples that lose elements and transform one into a lemon through time-based transitions. Five circles render initially, then sequential actions remove the last fruit, change the third fruit's type, and delete another element. The visualization uses d3 transitions with a 1000ms duration for positions, colors, and radii, while exit animations shrink removed elements to zero radius over 2000ms. The code applies d3.scaleOrdinal for color and radius mappings, and d3-selection’s enter/merge/exit pattern to handle nested circle and text elements.

Fork of Bowl of Fruit - General Update Pattern Special Cases

A dynamic SVG animation demonstrates the general update pattern for data joins, showing how enter, update, and exit selections handle changing fruit data. Five apples initially render as red circles, then sequentially: one apple is removed, one becomes a lemon, and another is filtered out. The code uses `d3.selectAll('circle').data(fruits)` with `.enter()`, `.merge()`, and `.exit()` methods, applying `transition().duration(1000)` for smooth radius changes. Fruit types map to colors and sizes via `scaleOrdinal`, with circles transitioning between states before removal.

Bowl of Fruit - General Update Pattern

Five circles representing fruit enter an SVG with zero radius and grow into apples. The example demonstrates D3’s general update pattern, animating exits by shrinking circles to zero and modifying existing fruits via the data join. Using `d3.scaleOrdinal` for color and radius, it transitions enter, update, and exit selections over one second. Hovering highlights a circle with a black stroke via mouse events. Over three seconds, `setTimeout` removes a fruit, changes a type to lemon, and filters another element, showing joins and transitions.

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.

Fruit - Update Pattern - Nested, Transitions

A bowl of fruit changes over time as apples are removed and one apple transforms into a lemon. The visualization demonstrates the D3 update pattern with nested elements. It uses d3.scaleOrdinal for color and radius, and applies d3.transition to animate position changes over 1200 milliseconds. Exit transitions shrink removed fruits over 500 milliseconds. The SVG rendering is driven by a custom fruitBowl function that merges entering and existing groups.

Bowl of Fruit - General Update Pattern Special Cases

Five pieces of fruit in a bowl demonstrate special cases of D3's general update pattern. Apples and lemons enter, exit, and update as a lemon replaces an apple and fruits are removed at intervals. The visualization uses d3.scaleOrdinal for color and radius, and d3 data joins with `.enter()`, `.merge()`, and `.exit()` to handle circles. Animated transitions are commented out, so changes appear instantly as one fruit is eaten at a time.
