This example presents a React-based dashboard for exploring an RSS feed. It displays a list of tree entries fetched from the Cabin Quest API and provides a button that opens the associated website in a new window. The visualization uses a custom hook, `useCabinQuest`, which relies on React's `useReducer` and `useEffect` to manage state and asynchronously fetch data via `fetch`. The interface is styled with CSS, and the data updates through the hook's dispatch actions.

react data loader

A React app demonstrates data loading with D3 utilities and state management through React hooks. The example uses `useState` and `useCallback` to manage asynchronous data, rendering a large message styled at 13em font size. The `index.html` file contains a static "Hello HTML!" placeholder, while the main `App` component awaits data before displaying content. The code imports `ReactDOM` for mounting and sets up a 960-by-500 pixel canvas area, though the rendering logic remains incomplete. The example illustrates a minimal pattern for integrating D3 data fetching with React’s component lifecycle.

[01] The Basics - Using React Hooks with D3

This example demonstrates how to combine React Hooks with D3 to render and update a simple SVG scatterplot. A `useState` hook manages an array of numeric data, while a `useRef` hook and `useEffect` hook initialize an SVG canvas using `d3.select` from D3 v5. Circles are appended via `selectAll(...).data(...).join('circle')`, with radius and position derived from each value. Clicking the “Update” button increments the data by 5, and “Filter” removes values over 35, triggering a re-render through React’s state changes.

React Hooks Bowl of Fruit

This example demonstrates a data visualization of a fruit bowl using React Hooks and D3.js. It shows a row of apple and lemon circles, where clicking a fruit selects it and highlights it with a black stroke. The code uses React's `useState` hook to manage the fruit data and selected fruit state, while D3's `scaleOrdinal` functions define the color and radius scales for each fruit type. The visualization renders as SVG circles within a React component, though the commented-out code suggests potential animation transitions that are not active.

useEffect

This example demonstrates the React useEffect hook by showing how a web application responds to user-triggered state changes. Three buttons—Posts, Users, and Comments—update a resource type displayed as a header, while the hook logs lifecycle events to the console on mount, on resource change, and during cleanup. The code uses React 16.9.0 with the useState and useEffect APIs directly from the React and ReactDOM UMD builds, and it renders the interface into a root div using ReactDOM.render.

Basic React Hook Test (Line - Fixed Data)

This example demonstrates a line chart built with React and D3 v5, using fixed sample data stored in component state. The visualization updates interactively when buttons increment every data point or filter out values exceeding a threshold. The code uses D3's `scaleLinear`, `line`, `curveCardinal`, `axisBottom`, and `axisRight` functions to render the SVG. A React `useEffect` hook redraws the chart whenever the state changes, while the `useRef` hook provides direct access to the SVG element for D3 selections.

React Hooks Starter

A React Hooks demonstration shows a grid of apple emoji whose count starts at 24 and adjusts with plus/minus buttons. The `Tree` component uses `React.useReducer` to manage the count state, while `React.useEffect` tracks mounting and updates a status message. Each apple renders through a separate `Apple` component that sets a message via `React.useState`. The code uses React 16.10 UMD builds and plain CSS for button styling, with the interactive behavior centered on toggling the reducer actions.

Fork of [07] Gauge Chart - Using React Hooks with D3

This example demonstrates a gauge chart built with React Hooks and D3 v5, where users can resize a video element and a draggable container while buttons adjust, filter, or append data values. The gauge renders as an animated SVG arc using `d3.arc` and `d3.pie`, transitioning between states via `transition.attrTween` with `d3.interpolate`. A separate bar chart uses D3 scales and axes with a `ResizeObserver` custom hook to handle dynamic container dimensions. Data updates trigger React state changes, which re-render both visualizations.

Redndering data with React

This example demonstrates how to render a dataset of CSS named colors as horizontal color swatches using React’s state management. The app loads CSV data from a GitHub gist via `d3.csv`, then uses React’s `useState` and `useEffect` hooks to fetch and store the data asynchronously. Once loaded, each row’s `Hex rgb` value is mapped to a div element with a corresponding background color, producing a stacked visual list. The interface also displays a “Loading...” message while the data is pending.
