This example demonstrates a data visualization design pattern using React and D3 v5, showing animated transitions of fruit shapes within a bowl. It displays how SVG elements update when data changes, with apples transforming into lemons and fruits being removed. The code uses `scaleOrdinal` and `scaleLinear` for sizing and positioning, while `selection.join()` and `transition` methods animate the changes. Population data from the World Bank is referenced, though the visualization focuses on the state management and rendering pattern for dynamic datasets.

Lesson 4: Design Pattern

This example demonstrates the design pattern of using a single SVG element to render and update a data-driven visualization with animated transitions. It shows a bowl of fruit, represented by colored circles, where an apple is converted to a lemon and a fruit is removed over time, illustrating how D3’s data join, along with `selection.enter()` and `selection.exit()`, manages dynamic updates. The code uses `d3.scaleOrdinal` and `d3.scaleLinear` to map fruit types to sizes and positions, and leverages `transition().delay()` for animated attribute changes. The visualization is built with D3 v5 within a React framework, rendering to SVG with a population dataset from the World Bank.

Lesson 4: Design Pattern

This example demonstrates a reusable color legend design pattern using React and D3 v5. It displays a vertical color scale with circular swatches and labels, generated through a custom `legends` function that uses `scaleOrdinal` and `range` for positioning. The visualization also includes an animated fruit bowl component defined in `makeFruit.js`, though it is not fully integrated into the main view. The code references population data from the World Bank and renders SVG elements with smooth transitions.

Lesson 4: Unidirectional Data Flow

This example demonstrates a unidirectional data flow pattern in React, where a fruit bowl visualization updates in response to state changes. A row of apples and lemons animates as fruits are added, removed, or transformed, with mouse hover actions triggering visual outlines. The code uses D3 v5 for SVG rendering, including transitions, scales, and selection joins, within a React framework. Data is generated programmatically, not from the provided CSV, and animations occur on timed intervals.

Bowl of Fruit - General Update Pattern

This example demonstrates the general update pattern for animated data visualizations with SVG. It shows a row of fruits—apples and lemons—that change over time as items are added, removed, or modified, with each fruit’s size and color derived from its type. The code uses D3 v5’s `scaleOrdinal` for color and radius mappings, and employs the `selection.merge()` and `selection.exit()` APIs to handle enter, update, and exit states dynamically. The React framework orchestrates timed updates to the fruit array, triggering re-renders that morph the visualization.

General update pattern

This example demonstrates the general update pattern for animated transitions in D3.js visualizations. A fruit bowl graphic shows a row of apples and lemons as colored circles, with changes occurring over time as fruits are removed, replaced, and filtered from the dataset. The implementation uses D3 v5’s selection merging and exit/enter methods within a React framework, rendered as SVG elements. The `fruitBowl` function applies ordinal color and radius scales to map fruit types to visual properties, while the main script manipulates the fruit array with setTimeout calls to trigger the update pattern.

Bowl of Fruit - General Update Pattern

This example demonstrates the general update pattern in D3.js, animating a bowl of fruit rendered as SVG circles and text labels. The visualization shows how data joins handle entering, updating, and exiting elements: five apples initially appear, then one is eaten, another transforms into a lemon, and a third disappears. Using `selection.data()` with a key function, `.enter()`, `.merge()`, and `.exit()` transitions, circles smoothly shrink, change color via `scaleOrdinal`, and reposition over one-second durations. The React framework wraps the D3 v6 code, with `d3.select` and `range` driving the state changes.

Bowl of Fruit - General Update Pattern

This example demonstrates the D3.js general update pattern with an animated bowl of fruit, showing apples and lemons as circles with color-coded fills. The code uses `selection.data()`, `selection.enter()`, and `selection.exit()` to manage joining data to SVG elements, with `transition().duration(500)` animating circle radii and text positions on updates. A `scaleOrdinal` maps fruit types to colors and sizes, while timed `setTimeout` calls trigger sequential data mutations—removing items, changing types, and adding fruits—to illustrate enter, update, and exit transitions. The rendering relies on D3 v5 within a React framework, using SVG and explicit animation transitions.

World population data set

Animated fruit bowl visualization shows a sequence of apples and lemons appearing, disappearing, and transforming within a rounded rectangular container. Built with React and D3 v5, the code uses selection joins to bind fruit data to SVG groups, with `transition().duration(1000)` animating color and radius changes through ordinal scales. The scene cycles through five timed updates, demonstrating enter, update, and exit patterns.
