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 - 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.

General Update Pattern

This example demonstrates the general update pattern in D3.js by animating a sequence of fruit circles in an SVG bowl. It shows how elements are added, modified, and removed over time—an apple disappears, one apple turns into a lemon, and another apple is deleted. The visualization uses the D3.js `select`, `selectAll`, and `transition` APIs to handle entering, updating, and exiting circles, with `scaleOrdinal` mapping fruit types to colors and radii. A timer-driven script triggers changes to the array of fruit objects, which the `fruitBowl` function renders with a one-second transition animation.

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 Bowl of Fruit - General Update Pattern

This example demonstrates D3’s general update pattern by animating a bowl of fruit represented as SVG circles. Apples and lemons enter, update, and exit with smooth radius transitions over one second. The code uses `d3.scaleOrdinal` for color and radius mappings, `selection.data()`, `enter().append()`, `merge()`, and `exit().remove()` inside a React-compatible `fruitBowl` function. Data changes are triggered by `setTimeout` calls that pop, replace, or filter items from an array, showcasing how D3 binds and reconciles data with animated visual updates.

General Update Pattern

A colorful bowl of fruit demonstrates D3's general update pattern using SVG circles and animated transitions. The `fruitBowl` function binds an array of fruit objects to circles, employing `selection.enter`, `selection.merge`, and `selection.exit` to handle additions, updates, and removals. `d3.scaleOrdinal` maps fruit types to fill colors and radius sizes, while `transition` animates positions and sizes. Timers in `index.js` trigger state changes, popping fruits, swapping an apple for a lemon, and removing items, showing how circles gracefully grow, shrink, or disappear over one-second intervals.

Bowl of Fruit - General Update Pattern

This example demonstrates D3’s general update pattern for binding data to SVG circles, showing how entering, updating, and exiting elements transition smoothly as fruit data changes over time. A bowl of apples shrinks as fruits are removed, one apple changes into a lemon, and another apple is filtered out, with each state change animated via `transition().duration()`. The code uses `scaleOrdinal` for color and radius mappings, `selection.data()` with a key function on fruit IDs, and explicit `.enter()`, `.merge()`, and `.exit()` chains to manage the circle lifecycle. Rendering targets SVG, driven by `d3.select` and `range` in a vanilla JavaScript setup.

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.
