This example renders an SVG circle that follows the mouse cursor across a 960 by 500 pixel viewport. The React component tracks pointer coordinates through an `onMouseMove` handler, storing them in state via `useState` and `useCallback`. The circle’s `cx` and `cy` attributes update reactively with each mouse movement, using React’s virtual DOM to re-render the SVG. The code imports React, ReactDOM, and D3 v7, though the interaction relies entirely on React’s event system and state management rather than D3-specific APIs.

Mouse Follower

A mouse follower example renders a single SVG circle that tracks the cursor's position within a 960 by 500 viewport. Using React state hooks (`useState` and `useCallback`), the component updates the circle's `cx` and `cy` coordinates on every `mousemove` event. D3 version 7 is loaded for potential utilities, though the interaction relies solely on React's event handling and SVG rendering. The circle starts centered and moves fluidly, demonstrating simple interaction between DOM events and React's declarative UI updates.

Mouse Follower

A React-controlled SVG circle follows the mouse cursor across a fixed 960×500 viewport. Mouse coordinates are captured by the SVG’s `onMouseMove` event, processed via a `useCallback` hook, and stored in React state with `useState`. Each movement updates the circle’s `cx` and `cy` attributes, causing a re-render. The example demonstrates direct state-driven SVG updates without D3-specific interaction APIs, relying solely on React’s event handling and DOM reconciliation.

Mouse Follower

A circle follows the mouse cursor as it moves across an SVG canvas. The React component tracks pointer coordinates via the `onMouseMove` event and updates the circle’s `cx` and `cy` attributes through `useState` and `useCallback`. Rendered with D3 v5’s SVG helpers within React 16.9, the example demonstrates real-time state-driven positioning without external data.

Mouse Follower

A plain SVG circle follows the user's mouse cursor across a 960-by-500 canvas. The React component tracks `clientX` and `clientY` from a `mousemove` event handler, updating state to reposition the circle's `cx` and `cy` attributes. The example uses React's `useState` and `useCallback` hooks, with D3 v7 loaded for potential supplementary utilities, though rendering relies solely on SVG elements and React's declarative updates.

Mouse Follower

A circle follows the mouse cursor within an SVG canvas, updating its position in real time as the pointer moves. Built with React, the application tracks mouse coordinates using an `onMouseMove` event handler and stores them in state via `useState`. The circle’s `cx` and `cy` attributes are bound to this state, and the SVG is rendered through ReactDOM. D3.js is included but not used for drawing; the interaction relies solely on React’s event system.

Mouse Follower

An interactive SVG visualization renders a single circle that follows the mouse cursor across a 960-by-500 canvas. The React component tracks pointer movement via the `onMouseMove` event and updates the circle’s `cx` and `cy` attributes through `useState` and `useCallback`. Initially positioned at the canvas center, the circle moves smoothly with the cursor. The example demonstrates state-driven rendering in React 17 with D3 v7, using plain SVG elements rather than data joins or scales. No external data source is involved; the visualization purely reacts to user input.

MouseFollower

A circle follows the mouse cursor across an SVG canvas, updating its position in real time as the pointer moves. The example uses React state with the `useState` and `useCallback` hooks to track mouse coordinates, which are passed as `cx` and `cy` attributes to a D3 v7-generated circle element. The SVG itself handles mouse movement events via `onMouseMove`, while the ReactDOM library renders the component into the DOM.

Mouse Follower

A React application renders an SVG circle that follows the mouse cursor across a 960-by-500 viewport. The component tracks pointer coordinates via the `onMouseMove` event handler, updating React state with the client X and Y positions, which are then bound to the circle's `cx` and `cy` attributes. The visualization demonstrates real-time state-driven SVG manipulation using React hooks (`useState`, `useCallback`) and ReactDOM, with no external data source or animation library.
