A React component renders an SVG circle that follows the mouse cursor across a 960×500 viewport. The app uses React hooks `useState` and `useCallback` to track pointer coordinates from `onMouseMove` events, updating the circle’s `cx` and `cy` attributes. The example demonstrates integrating D3’s `arc` import while relying on React’s declarative rendering for state-driven SVG updates, with a static yellow circle illustrating callback-driven interactivity.

Interaction with React

This example shows a single yellow circle that follows the mouse cursor across a 960-by-500 SVG canvas. Built with React 16.9 and D3 v5, the app uses the `useState` and `useCallback` hooks to track the cursor’s `clientX` and `clientY` coordinates, updating the circle’s `cx` and `cy` attributes on every `mousemove` event. The D3 `arc` import is included but unused in the visible code.

interaction with react

A React component renders an SVG circle that tracks the mouse position across the full viewport. The circle’s center coordinates update via React state, with the `onMouseMove` event handler feeding client coordinates into a `useState` hook. D3 v5 provides the `arc` import, though the visible geometry relies on plain SVG circle elements. The example demonstrates bidirectional integration of D3’s ecosystem with React’s declarative state management, using the `useCallback` hook to optimize event handling. No data source is involved; the visualization is purely interactive, responding to user input in real time.

Interaction with React

This example demonstrates a React-based SVG visualization where a circle follows the mouse pointer across a 960-by-500 viewport. It shows how mouse events and unidirectional data flow manage interactive state in React, using the `useState` hook to track cursor coordinates and `useCallback` for the event handler. The single-circle rendering, with a white inner circle, updates its `cx` and `cy` attributes on every `onMouseMove` event, relying on D3 v6 for SVG utilities and React 16 for component rendering.

React interactive

A yellow circle follows the mouse cursor across an SVG canvas, updating its position in real time as the user moves the pointer. The visualization demonstrates React state management with D3, using the `useState` hook to track mouse coordinates and passing them as `cx` and `cy` attributes to the circle element. The app renders through ReactDOM, while the SVG is defined directly in JSX, with no external data source.

ReactD3.1

The example shows a single circle that follows the mouse cursor across an SVG canvas, with its center position updated in real time. It uses React’s `useState` and `useCallback` hooks to track mouse coordinates via an `onMouseMove` event handler, and renders the circle with SVG elements. The visualization relies on React 16.9 and ReactDOM for rendering, with no additional D3 modules or data sources, demonstrating a minimal integration of interactive state management with SVG output.

A program that follows your mouse with a circle

A circle follows the mouse cursor across an SVG canvas. The visualization uses React state to track the cursor's pixel coordinates and updates the circle's center position on every mouse move. The code imports the `arc` function from d3 but does not use it; rendering is handled entirely through React's declarative SVG elements. The example demonstrates a simple interactive pattern using React's `useState` and `useCallback` hooks within a D3-styled viewport.

Mouse follower

A React application renders an SVG circle that tracks the mouse cursor in real time. The circle's position updates via React's `useState` and `useCallback` hooks, which handle `mousemove` events on the SVG element. The example demonstrates simple interactive rendering with D3's `arc` import unused, relying instead on React's declarative state management. The visualization uses a 960x500 SVG canvas with a fixed circle radius, showing how React can manage dynamic visual updates without explicit D3 selection or transition APIs.

React sample

A React component renders an SVG circle that follows the mouse cursor across a 960×600 viewport. The application tracks pointer coordinates through the `onMouseMove` event handler and stores them in state using the `useState` hook. The circle's `cx` and `cy` attributes update reactively as the `mousePostion` state changes, demonstrating a direct integration of React's declarative rendering with SVG. D3.js v6 is loaded but not actively used in this example, which instead relies purely on React 17 and ReactDOM for all interactivity and rendering.
