This example demonstrates a dynamic data update pattern for a simple scatterplot of fruit represented as colored circles. Using D3 v5’s data join, it animates the position and size of each fruit as items are added, removed, or changed in type, with transitions that smoothly adjust the `cx` and `r` attributes. The code uses `d3.range`, `selection.data`, `.enter()`, `.merge()`, and `.exit()` to manage changes, and `d3.scaleOrdinal` to map fruit types to sizes. The dataset is manually manipulated with `setTimeout` calls, simulating an eating and refilling sequence.

Bowl of Fruit - General Update Pattern

A dynamic scatterplot-style visualization demonstrates D3's general update pattern with a bowl of fruit metaphor. Apples and lemons, rendered as colored circles with labels, shuffle positions as the dataset changes over time through a timed script. The example uses D3 v5's `selection.enter()`, `merge()`, `exit()`, and `.transition()` APIs to animate additions, removals, and type changes with 1000ms duration tweens. SVG elements update their `transform`, `fill`, `r`, and `text` attributes accordingly, while a random `id` key tracks each fruit through the data lifecycle.

Bowl of Fruit - General Update Pattern

This example demonstrates the general update pattern in D3, showing how data joins handle entering, updating, and exiting elements. It renders a row of fruit as SVG circles, with apples and lemons distinguished by a `scaleOrdinal` color scale and radius scale. The code uses `selection.data()` with a key function, then applies transitions to animate new circles scaling up from radius zero, existing ones updating position and size, and removed fruits shrinking away before being deleted. The animation is driven by `setTimeout` calls that modify the fruit array and re-render.

need some fruit - General Update Patterns

This example demonstrates D3.js general update patterns by rendering a bowl of fruit as colored circles that change over time. The visualization shows apples and lemons entering, exiting, and updating their position, size, and color through staggered transitions. Using the `data` join with key functions and `merge`, the code animates SVG circles via `transition().duration()`, applying `scaleOrdinal` color and radius scales based on fruit type. The data source is a JavaScript array modified with `setTimeout` calls to simulate eating and replacing fruit.

Bowl of Fruit - General Update Pattern

This example demonstrates the general update pattern in D3 for animating changes to a dataset. It shows a row of circles representing fruit, starting with five apples, then removing one, swapping an apple for a lemon, and removing another. The visualization uses d3.v5 to bind data to SVG circle elements, with enter, update, and exit selections to handle additions, modifications, and deletions. The `fruitBowl` function explicitly uses `.enter().append()`, `.merge()`, and `.exit().remove()` to manage the lifecycle of each circle, and uses `scaleOrdinal` to map fruit types to colors and radii.

Bowl of Fruit - General Update Pattern

Animated SVG demonstrates the D3 general update pattern with a bowl of fruit. Five apples render as colored circles, then a data join removes, replaces, and filters fruits through timed intervals. D3 v5’s `selection.data`, `enter`, `merge`, `exit`, and `transition` animate circle radii and positions, while `scaleOrdinal` maps fruit types to colors and sizes. The example updates a static dataset through explicit function calls, showing enter, update, and exit behaviors with smooth 1-second transitions.

Bowl of Fruit - General Update Pattern

A dynamic SVG visualization demonstrates the general update pattern in D3 v5, where fruit appears as colored circles that grow, shrink, and change color as apples are eaten and replaced with lemons. The fruitBowl module uses d3.scaleOrdinal for color and radius scales, with enter, merge, and exit selections chained to transition.attr for smooth 1000-millisecond animations. Data updates triggered by setTimeout calls modify the fruits array, showing how keyed data joins handle additions, removals, and modifications while maintaining circle identity.

Bowl of fruit general update pattern

This example demonstrates the general update pattern for data joins in D3 v5, showing how a bowl of fruit responds to dynamic changes in an array. The visualization renders apples, lemons, and grapefruits as circles with distinct radii and colors, using `scaleOrdinal` for both color and radius mappings. As the data changes through timed events—removing fruits, swapping an apple for a lemon, and adding a grapefruit—the SVG elements transition smoothly over 1000 milliseconds. The code uses D3's `selectAll`, `data`, `enter`, `merge`, and `exit` methods within a React framework, with a bowl drawn as a rectangle behind the fruit.

Bowl of Fruit - General Update Pattern Special Cases

This example demonstrates the general update pattern for dynamic data visualizations, tracking five fruits in a bowl as they change over time through scripted modifications. It shows how items are added, removed, and have their attributes updated, with a visual distinction between apples and lemons using different colors and radii. The code uses D3 v5's selection merging and transitions to animate position, size, and text placement, while clicking a fruit highlights it with a black stroke. The data is a simple array of fruit objects, with each state change triggered by a timeout and rendered via the `fruitBowl` function.
