Fork of Bowl of Fruit - General Update Pattern Special Cases

This example demonstrates the general update pattern in D3 v5, showing how to handle adding, removing, and modifying data elements in a visualization. A bowl of fruit is rendered as circles with labels, using `scaleOrdinal` for color and radius mappings. The code uses `selection.selectAll`, `enter()`, `merge()`, and `exit()` to update the SVG scene over time, with timeout-driven changes removing an apple, replacing one with a lemon, and filtering the array. The rendering uses SVG primitives like `circle` and `text`.

This example demonstrates the general update pattern for SVG elements, showing how a fruit bowl changes over time with apples and lemons added and removed. A JavaScript array acts as the data source, modified through pop, assignment, and filter operations. Using functions from `d3` including `select`, `range`, and custom `fruitBowl` logic with `scaleOrdinal` for colors and radii, the view updates render enter, update, and exit states on circles and text labels. The visualization relies on D3 v5’s selection merging and exit removal to reflect data changes.

This example demonstrates the general update pattern for SVG elements in D3 v5, showing how to handle special cases like creating, updating, and removing data points in a static visualization. A bowl of fruit changes over time as apples are eaten or replaced with lemons, with each fruit rendered as a circle and text label. The code uses D3's `selectAll` and `merge` methods to reconcile entering, updating, and exiting elements, while `scaleOrdinal` maps fruit types to colors and radii. The SVG view updates at timed intervals to reflect the changing array of fruit objects.

This fork of the Bowl of Fruit example demonstrates the general update pattern for handling special cases in D3 v5 with SVG rendering. It shows a static bowl containing apples and a lemon, with fruits being removed and modified over timed intervals. The code uses `d3.select`, `d3.range`, `scaleOrdinal` for color and radius mapping, and the `.merge()` API to manage enter, update, and exit states for groups representing each fruit. The data is a JavaScript array of fruit objects that is mutated to trigger re-renders.

This example demonstrates the general update pattern for SVG elements in D3 v5, showing how a bowl of fruit changes as apples are eaten or replaced by lemons. Three distinct update scenarios occur sequentially: removing the last apple, changing an apple’s type to lemon, and filtering out an apple from the middle. The `fruitBowl` function uses D3’s `selectAll` and `.merge` with ordinal scales for color and radius to handle entering, updating, and exiting groups. The underlying code uses `d3.select` and `d3.range` to manage the data array, while SVG `rect` and `circle` elements are re-rendered at each timeout-driven step.

This example demonstrates D3’s general update pattern for changing data arrays, showing how to add, remove, and modify elements in an SVG scene. Five apples are initially drawn, then one is removed, one is replaced by a lemon, and another apple is deleted, with each change re-rendering the bowl. The code uses D3’s `select`, `selectAll`, `enter`, `merge`, and `exit` methods to handle node creation, updating, and removal, alongside `scaleOrdinal` for color and radius mapping. The scene renders in SVG with circles and text labels, driven by timed `setTimeout` calls.

This example demonstrates the General Update Pattern in D3, showing how to handle add, remove, and modify operations on SVG fruit shapes. The code uses D3 v5's `selection.enter`, `selection.merge`, and `selection.exit` to update circles and text elements. The iteractive sequence buys apples, then eats one, replaces one with a lemon, and removes another, with each change re-rendering the bowl using the `fruitBowl` function that imports `scaleOrdinal` for color and radius mapping.

This example demonstrates the general update pattern for handling dynamic data changes in D3.js v5, showing how SVG elements are added, removed, and modified in response to a sequence of timed events on a bowl of fruit. The visualization starts with five apples, then removes one, changes one apple into a lemon, and removes another apple, all while using `selection.selectAll`, `.enter()`, `.merge()`, and `.exit()` to manage the lifecycle of `g` groups containing circles and text labels. The code applies `scaleOrdinal` for both color and radius scales, mapping fruit types to specific visual properties, and uses `setTimeout` to trigger each update transaction.
