This example demonstrates the D3 general update pattern by animating a bowl of fruit, where circles representing apples and lemons appear, disappear, and change color through data-driven transitions. It shows enter, update, and exit selections working together as fruits are eaten or replaced over time. The code uses `selection.data()` with a key function, `selection.enter()`, `selection.merge()`, and `selection.exit()` alongside `transition()` for smooth radius and position changes. D3’s `scaleOrdinal` maps fruit types to colors and radii, while `Math.random()` generates unique IDs for each fruit.

Bowl of Fruit - General Update Pattern

This example demonstrates the D3 general update pattern with a bowl of fruit animation. It shows how data joins handle entering, updating, and exiting elements: apples disappear, one apple transforms into a lemon, and fruit positions shift accordingly. The code uses `selection.data()`, `selection.enter()`, `selection.exit()`, and `selection.merge()` within a custom `fruitBowl` function, animating circle radii via `transition().duration(1000)`. Fruits are generated with `d3.range` and `Math.random()` IDs, rendered as SVG circles and text elements with a `scaleOrdinal` color scale.

Bowl of Fruit - General Update Pattern

This example demonstrates the D3 general update pattern by animating a bowl of fruit rendered as SVG circles. Apples and lemons appear as red and yellow circles with different radii, with enter, update, and exit transitions over one-second durations. The code uses `selection.data` with a key function, `merge`, `transition`, and `attr` to handle dynamic changes. D3’s `scaleOrdinal` maps fruit types to colors and sizes, while `setTimeout` schedules fruit removal and type replacement events.

Bowl of Fruit - General Update Pattern

A bowl of fruit demonstrates the D3 general update pattern for enter, update, and exit selections. Apples and lemons enter as circles that scale up from radius zero, update their fill color and size through a one-second transition, and exit by shrinking away. The code uses `selection.data`, `selection.enter`, `selection.merge`, and `selection.exit` with `transition.attr` to animate SVG circles, while `scaleOrdinal` maps fruit types to colors and radii. Data changes are triggered by `setTimeout` calls that remove, replace, or filter items from the fruits array.

Bowl of Fruit- General Update Pattern

This example demonstrates the general update pattern in D3 by animating a bowl of fruit represented as circles. It shows how data joins handle entering, updating, and exiting elements: apples appear, one is removed, another changes to a lemon, and a third disappears. The code uses `selection.data`, `.enter()`, `.merge()`, `.exit()`, and `transition.attr`. It relies on `d3.scaleOrdinal` for color and radius scales, and renders with SVG circles in a fixed 960×500 viewport. Animated transitions adjust circle positions and radii over one-second durations.

Bowl of Fruit - General Update Pattern

This example demonstrates the general update pattern in D3 v5, animating a bowl of fruit as apples are eaten, replaced with lemons, and removed. It shows how data joins handle enter, update, and exit selections, with circles transitioning their radius and position over one-second durations. The code uses `scaleOrdinal` for color and radius mappings, `selection.merge()` to combine enter and update states, and chained `transition().duration()` calls for smooth SVG animations. Random IDs track each fruit, ensuring stable element binding across state changes.

Bowl of Fruit - General Update Pattern

This example demonstrates D3’s general update pattern by animating a bowl of fruit as apples are added, removed, or converted to lemons. Circles and labels enter, update, and exit with staggered transitions, using keyed data joins and ordinal scales for color and radius. The code relies on `selection.enter`, `merge`, `exit`, and `transition` to animate position, size, and fill over one-second durations. SVG rendering with D3 v5 drives the visualization, which is orchestrated by timed function calls in `index.js`.

Bowl of Fruit - General Update Pattern

This example demonstrates the general update pattern in D3 by animating a bowl of fruit as apples are eaten and replaced with lemons over time. The code uses `selection.data()`, `enter()`, `merge()`, and `exit()` to handle circles and text labels, with `d3.scaleOrdinal` mapping fruit types to colors and radii. Rendering occurs as SVG within a fixed-width viewport, driven by a simple `render()` function called after each timed mutation to the fruits array. The visualization relies on D3 v5 and vanilla JavaScript to coordinate data joins and smooth transitions.

Bowl of Fruit — General Update Pattern + Transitions

A bowl of fruit animates through the D3 general update pattern, demonstrating enter, update, and exit selections with smooth transitions. Apples and lemons appear as colored circles, scaling radius and shifting horizontally as items are added, removed, or change type over time. The example uses d3-selection's `selectAll`, `data`, `merge`, and `exit` methods, along with `transition().duration()` to animate SVG circle attributes. A color scale and radius scale map fruit types to visual properties, while randomly generated IDs track elements across updates.
