D3 Starter - General update pattern Modular way

This example demonstrates the D3 general update pattern in a modular way, using animated fruit bowls to illustrate how data changes drive SVG circle and text elements. The code defines a reusable `fruitBowl` function that handles enter, update, and exit transitions for circles and labels, with `transition().duration(1500)` animating position, radius, fill color, and opacity changes. Using d3.v6's `scaleOrdinal` for color and radius mapping, the visualization cycles through adding, removing, and modifying fruit data points via `setTimeout` calls.

D3 Starter - General update pattern Nest grouped version

This example demonstrates the D3 general update pattern with a nested group structure, showing how a data array of fruit items maps to SVG circles and text labels. The data starts with five apples, then animates through a lemon replacing an apple, and two apples being removed, all at one-second intervals. Using `d3.select` and `d3.range`, the `fruitBowl` function appends `<g>` groups, merging enters and updates, while exits are removed. It uses ordinal scales for color and radius based on fruit type, rendering with SVG.

D3 Starter - General update pattern Modular way with Bowl

This example demonstrates the general update pattern in D3 using a modular function `fruitBowl` that renders a bowl with fruit circles. It shows how enter, update, and exit transitions handle dynamic data changes, animating fruits in and out as apples are consumed and one apple becomes a lemon. The code uses d3's `scaleOrdinal` for color and radius mapping, `selectAll`, `enter`, `merge`, and `exit` methods with `.transition()` for smooth animations. Data is generated with `range` and `Math.random()` IDs, rendered as SVG elements.

d3 Starter Bowl of Fruit - General Update Pattern

This example demonstrates the "general update pattern" in D3.js v5 by rendering a static bowl of fruit—a set of apples and a lemon—as SVG shapes. The visualization dynamically updates the fruit bowl through a series of timed events, removing apples, replacing one with a lemon, and filtering out another, using the `selectAll`, `enter`, `merge`, and `exit` methods (e.g., `selection.selectAll('g').data(fruits)`, `groups.enter().append('g')`) to handle element creation, updating, and removal. The code uses D3's `scaleOrdinal` for color and radius mapping, with the SVG rendered directly as `rect`, `circle`, and `text` elements. Data is generated via `range(5)` and `makeFruit` functions, reacting to `setTimeout` callbacks that call `render()`.

D3 Starter - General update pattern

Five fruit circles render as apples in an SVG created with D3 v6. A function called `render` demonstrates the general update pattern by joining data to circles with `selectAll` and `data`, then handling enter, update, and exit selections. The code uses `scaleOrdinal` for color and radius based on fruit type, and `merge` to apply shared attributes. After one second, a fruit is removed; after two, an apple becomes a lemon, showing transitioned states.

D3 Starter - General update pattern Nest grouped version w/transition

This example demonstrates the D3 general update pattern with nested groups, animating a fruit bowl where apples are eaten or replaced by lemons over time. The visualization uses d3.selectAll and data joins to bind fruit objects to SVG group elements, with transitions on circle radii and positions. The code leverages d3.scaleOrdinal for color and size mapping, while enter, merge, and exit selections handle dynamic updates. The animation sequence includes removing apples, changing a fruit type, and filtering the dataset.

Bowl of Fruit - General Update Pattern

This example demonstrates the D3 general update pattern by rendering a bowl of fruit as SVG circles that change over time. Using `d3.scaleOrdinal` for color and radius mapping, the `fruitBowl` function joins data to circle elements, handling enter, update, and exit selections with `.enter()`, `.merge()`, and `.exit().remove()`. Apples and lemons are distinguished by type, and timed interactions remove fruits or replace an apple with a lemon, showing how the visualization synchronizes DOM elements with changing data.
