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.

Lesson 4: Design Pattern

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.

Click to Select: Interaction with Unidirectional Data Flow

Five fruit circles animate in and out of a bowl, and clicking one selects it with a navy stroke. The example demonstrates unidirectional data flow where React-like state changes trigger a re-render that updates SVG circles via D3’s data join and `transition` for smooth radius and fill changes. It uses `scaleOrdinal` for color and size, `selectAll` with key functions, and `merge`/`exit` for enter-update-exit patterns. The code shows automatic updates as fruits are removed or replaced without direct DOM manipulation.

Hover to Select: Interaction with Unidirectional Data Flow

Five fruit circles render in an SVG using D3 v5 within a React framework, with apples and lemons distinguished by ordinal color and radius scales. Hovering over a circle triggers a navy stroke via mouseover and mouseout events, updating a selectedFruit state variable that flows unidirectionally into the fruitBowl render function. Transitions animate circle entry, exit, and size changes over one-second durations as the fruit array is modified through pop and type replacement operations.

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.

D3 Course 6: Interaction with Unidirectional Data Flow

This example demonstrates interactive selection and highlighting of fruit marks in an SVG bowl, with click and hover events triggering updates through a unidirectional data flow. The fruit bowl renders apples and lemons as circles using a D3 data join, with transitions animating size and position changes. Clicking a fruit selects it with a black stroke, while hovering applies an orange stroke, managed by callback props passed from the main script. The code uses D3 v5 APIs including `scaleOrdinal` for colors and radii, `selection.on` for event listeners, and `transition.duration` for smooth updates across three timed state changes.

Untitled

A bowl of fruit demonstrates the D3.js general update pattern with animated transitions. Circles represent apples and lemons, color-coded via a d3.scaleOrdinal and sized with another ordinal scale. The example renders to SVG and uses d3.transition to animate entering, updating, and exiting elements over one-second intervals. State changes—removing fruit, changing an apple to a lemon, and filtering the array—trigger the React-wrapped fruitBowl function to update the visualization dynamically.

General update pattern

The example demonstrates the D3 general update pattern, animating a row of fruit circles as apples are added, removed, and replaced with lemons over time. It uses d3.select and d3.range to manage data, and the fruitBowl module applies enter, merge, and exit selections with transition.attr to animate circle radius and fill color. Rendering occurs in SVG via a React-free vanilla JavaScript setup, with d3.scaleOrdinal mapping fruit types to colors and sizes. The data consists of a mutable array of fruit objects, each with a random id for keying.
