D3 Starter - General update pattern

D3 Starter - General update pattern Nest

This example demonstrates the D3 general update pattern for data-bound SVG elements, using a fruit bowl metaphor to show how enter, update, and exit selections handle changing data. The code uses `d3.scaleOrdinal` to map fruit types (`apple`, `lemon`) to colors and radii, with each fruit’s position derived from its index. Over timed intervals, `setTimeout` triggers removal of apples, mutation of one apple to a lemon, and filtering of another fruit, while the `fruitBowl` function merges `enter` and `update` selections and applies transitions to exit circles. Rendering is SVG-based, with text labels showing fruit types.

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 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 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.

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.

General Update Pattern

This example demonstrates D3.js’s general update pattern for binding data to SVG circles, rendering a row of apples that changes over time. It shows how entering, updating, and exiting elements are handled by merging selections and calling `selection.exit().remove()`. The code uses `d3.scaleOrdinal` for color and radius mappings, and `d3.range` to generate initial fruit data. After one second, an apple is removed; after two, one apple changes to a lemon. The visualization relies on SVG circles and explicit `attr` updates without transitions.

D3 General Update Pattern

A D3 visualization demonstrates the general update pattern for handling data joins with animated transitions. It renders five circles as apples using SVG, with the `fruitBowl` function managing enter, update, and exit selections via `selection.data()`, `.enter()`, `.merge()`, and `.exit()`. Sequential timeouts trigger state changes: removing a fruit, replacing an apple with a lemon (changing color and radius via ordinal scales), and filtering out another item. Each update animates circle radii from zero to a scaled value over 1000 milliseconds using `.transition().duration()`.

Bowl of Fruit - General Update Pattern

Five apples rendered as SVG circles in a bowl demonstrate D3’s general update pattern. The code uses `d3.scaleOrdinal` for color and radius, binding fruit data to circles via `selectAll` and `data`. A `setTimeout` removes the last apple, while another changes the third apple to a lemon, triggering enter, update, and exit selections with `circles.enter()`, `circles.attr`, and `circles.exit().remove()`. The visualization shows how D3 handles dynamic data changes smoothly.
