This example demonstrates interactive dragging of circles connected by lines, built by combining React state management with D3's rendering capabilities. The visualization shows three semi-transparent circles linked by thick black lines, where dragging any circle updates its position and the connecting lines follow in real time. React's `useState` and `setData` manage the data array, while D3's `drag()` handler and `select()` method handle the SVG rendering and pointer interactions. The `VizWrapper` component delegates visual updates to the `viz` function, which uses D3's `range` and `join` operations to redraw the network on each data change.

React & D3 Drag with useReducer

This example shows three draggable circles connected by thick black lines in an SVG canvas. The circles and lines are rendered and updated using D3.js selectors and join operations, while React manages the application state. Dragging any circle dispatches a `drag` action to a `useReducer` hook, updating the circle’s x and y coordinates in the central state object. The D3 `drag` handler triggers the callback, and the Vue-like wrapper re-renders the visualization via the `viz.js` module. Animated interactivity is demonstrated through mouse hover effects and real-time position updates.

Loading data with react & D3

A circle follows the mouse across the screen using unidirectional data flow in React with D3. The example demonstrates loading data and managing state through a custom `setState` callback, which triggers re-rendering of the SVG via d3-selection's `join` method. The `viz.js` module updates the circle's `cx` and `cy` attributes based on mouse events, initializing its position to the window's center. It uses D3 v7 with vanilla React, rendering through `d3.select` and `selectAll`.

Hello VizHub

This example demonstrates interactive circles on an SVG canvas, where users can drag each circle to reposition it or click to trigger a temporary scale-and-color animation. The visualization highlights D3 v5’s drag behavior and transition system, using chained transitions to enlarge circles to black and then restore their original size and color. It generates 20 randomly positioned circles with a fixed radius, colored via the `d3.schemeCategory10` palette. The code relies on `d3.create`, `d3.range`, `d3.drag`, and `selectAll().join()` to manage dynamic elements and event handling.

Loading Data with React & D3

This example demonstrates how to load and interact with data using D3 utilities within a React application. It renders an SVG circle that follows the mouse cursor, updating its position through D3’s event handling. The code uses `d3.select` to append an SVG element and a circle, then attaches a `mousemove` listener to update the circle’s `cx` and `cy` attributes based on cursor coordinates. The visualization is rendered via SVG, with the React app serving as the container for the D3-generated elements.

Loading Data with React & D3

This example shows a simple interactive visualization where a circle follows the mouse cursor across an SVG canvas. React state tracks the cursor's current x and y coordinates, updating the circle's `cx` and `cy` attributes on every mouse movement. The code combines React’s `useState` and `useCallback` hooks with ReactDOM to manage the UI, while the SVG scene renders a single circle element whose position is bound to the live mouse data. The interaction is driven by the `onMouseMove` event handler on the SVG, demonstrating direct state-to-rendering synchronization within a React-D3 pairing.

Loading data in react with d3

This example demonstrates a simple interactive visualization where a single circle follows the mouse cursor within an SVG canvas. It shows how to combine React’s state management with D3.js for rendering. The code defines a React component using `useState` to track mouse coordinates, and handles `onMouseMove` events to update the circle’s `cx` and `cy` attributes. It uses `d3.v6` for SVG handling and `ReactDOM.render` to mount the component, with the circle radius hard-coded as 30 pixels.

Loading data with React & D3

A React component renders a D3-selected SVG circle that follows the mouse pointer across the viewport. The example demonstrates unidirectional data flow: mouse events call `setState` to update coordinates, which triggers a re-render passing new state to a `viz` function. It uses `d3.select`, `.join('circle')`, and `.attr` to bind the circle’s position to state properties `x` and `y`. The initial state centers the circle, and the SVG resizes to the window dimensions.

Loading Data w/React and D3

This example demonstrates loading and managing data in a React visualization, where a single circle follows the mouse cursor across an SVG canvas. The app uses React’s `useState` hook to store the cursor’s x and y coordinates, and a `handleMouseMove` callback updates this state on every mouse movement. Rendering is handled by ReactDOM, which outputs the SVG circle with its position bound to the state. The code explicitly imports React and ReactDOM, and uses `useState` and `useCallback` for state management and event handling.
