Forked from Bowl of Fruit - General Update Pattern

This visualization demonstrates special cases of D3’s General Update Pattern for a dynamic “bowl of fruit.” It shows three sequential state changes—a fruit disappearing, one changing its type, and another being removed—while each circle’s radius and color scale ordinally by fruit type, and the bowl is a static rectangle. Using D3 v5’s `selectAll`, `.enter()`, `.merge()`, and `.exit()`, the code updates SVG groups and their circle/text children in place, with `scaleOrdinal` mapping apple and lemon to distinct colors and sizes. The SVG renders at 960×500, and the script drives changes via `setTimeout` callbacks.

Bowl of Fruit - General Update Pattern

A bowl of fruit demonstrates the D3 general update pattern as apples and lemons appear, disappear, and change type over time. The visualization uses D3 v5’s `selectAll`, `enter`, `merge`, and `exit` methods to handle data joins, with `scaleOrdinal` mapping fruit types to colors and radii. SVG circles and text elements within groups are updated, while a static rectangle represents the bowl. State changes trigger re-renders via `setTimeout`, showing how joins manage dynamic datasets.

Bowl of Fruit - General Update Pattern Special Cases

The bowl of fruit demonstrates special cases of D3’s general update pattern, showing how enter, update, and exit selections handle data changes. Five apples are drawn as circles with text labels; then an apple is removed, another is swapped for a lemon, and a third is filtered out. The code uses `d3.selectAll`, `data`, `enter`, `merge`, and `exit` to manage SVG groups, with `scaleOrdinal` mapping fruit types to radii and colors. The animation runs via `setTimeout`, with each step re-rendering the bowl shape and fruit positions.

Bowl of Fruit - General Update Pattern Special Cases

This example demonstrates the general update pattern in D3.js by animating a bowl of fruit through several state changes: removing apples, replacing one with a lemon, and filtering another. It shows how enter, update, and exit selections handle circles and text elements across these transitions. The code uses D3 v5 with `scaleOrdinal` for colors and radii, plus selection methods like `.merge()` and `.exit().remove()`. Rendered as SVG, the fruit bowl visualizes state changes through a timed sequence of data mutations.

Bowl of Fruit - General Update Pattern

An animated bowl of fruit demonstrates D3’s general update pattern, showing five fruits that disappear or change type over time. The SVG visualization uses a single reusable `fruitBowl` function, which binds data arrays to `g` groups via `selection.data()`, then handles enter, update, and exit selections with `enter().append()`, `merge()`, and `exit().remove()`. Fruit appearance relies on `scaleOrdinal` color and radius scales, while timed `setTimeout` calls trigger data mutations—removing apples or replacing one with a lemon—to illustrate smooth transitions in the rendered circles and labels.

Bowl of Fruit - General Update Pattern

This example demonstrates the D3 general update pattern with a bowl of fruit that changes over time. An SVG renders circles representing apples and lemons, with color and size determined by `d3.scaleOrdinal` scales. The `fruitBowl` function uses `selection.selectAll`, `enter()`, `merge()`, and `exit()` to handle data joins, while `setTimeout` triggers state changes—removing fruits and replacing an apple with a lemon—to show how the visualization updates dynamically.

Bowl of Fruit - General Update Pattern Special Cases

This example demonstrates the general update pattern's special cases by showing a bowl of fruit that changes over time: apples are eaten, one apple is replaced with a lemon, and another apple is removed. Using D3 v5’s `selectAll`, `enter`, `merge`, and `exit` methods, the code updates SVG groups and shapes incrementally. Ordinal scales from `d3` map fruit types to colors and radii, while `setTimeout` triggers sequential state changes in the data array.

Bowl of Fruit - General Update Pattern

This example demonstrates the general update pattern in D3 by showing a row of fruit circles that change over time—apples are removed, one apple transforms into a lemon, and another apple disappears. The code uses `d3.scaleOrdinal` to map fruit types to colors and radii, and `selectAll` with `.enter()`, `.merge()`, and `.exit()` to handle data joins. SVG circles are appended and updated based on a `fruits` array, with timers (`setTimeout`) triggering each state change.
