Mouse Follower

A circle tracks the mouse cursor across a full-browser SVG canvas. The React application uses the `useState` hook and a `handleMouseMove` callback with `onMouseMove` to update the circle's `cx` and `cy` attributes in response to pointer movement. The rendering relies on ReactDOM's `render` method to draw the single SVG circle element, with dimensions set from the window's inner width and height.

A circle rendered as an SVG element follows the mouse cursor across the full browser window. The React component tracks pointer coordinates via the `onMouseMove` event handler, storing them in state with the `useState` hook. It re-renders the circle's `cx` and `cy` attributes to match the cursor's `clientX` and `clientY` values, using `useCallback` for the event handler. The visualization demonstrates real-time pointer tracking with minimal code, relying on React's declarative rendering to update the SVG circle's position.

A single circle in an SVG viewport tracks the user's mouse in real time, following its position across the full screen. Built with React, the app uses the `useState` hook to store the current mouse coordinates and the `useCallback` hook to update them via the SVG `onMouseMove` event handler. The circle’s `cx` and `cy` attributes are bound directly to this state, causing a re-render on every pointer movement. The rendering approach is purely declarative, with the circle’s radius fixed at 30 pixels.

A circle follows the mouse cursor across a full-window SVG canvas, reacting in real time to pointer movement. The React component tracks mouse coordinates via the `onMouseMove` event, updating state with `useState` and `useCallback`, then re-renders the circle’s `cx` and `cy` attributes. The visualization uses React 16.9 and ReactDOM to render SVG elements directly in the browser.

A small circle tracks the mouse in real time across a full-window SVG canvas. The React component stores the pointer’s coordinates in state via `useState` and updates them on every `mousemove` event through `useCallback`. The circle’s `cx` and `cy` attributes are bound directly to the current mouse position, re-rendering on each movement. The example uses React 16.9 with `ReactDOM.render`, an SVG with inline event handling, and no external data source or animation library.

A circle follows the mouse cursor across a full-window SVG canvas. The React application tracks the cursor's client coordinates via an `onMouseMove` event handler, updating the circle's `cx` and `cy` attributes in real time. Written with React and ReactDOM, it renders through SVG elements without any external data source, relying solely on user interaction.

A circle tracks the mouse cursor across a full-window SVG canvas, responding to every pointer movement in real time. React state updates the circle’s center coordinates on each `mousemove` event, using the `useState` hook and a `useCallback` handler. The visualization renders with React 16.9 and SVG, with no external data source or animation library—only direct event-driven position updates.

A circle follows the mouse cursor across a full-screen SVG canvas, updating its center position in real time as the pointer moves. Built with React and ReactDOM, the application tracks mouse coordinates through an `onMouseMove` event handler and stores them in component state via the `useState` hook. The SVG circle’s `cx` and `cy` attributes are bound to this state, causing React to re-render the shape at each new location. The canvas dimensions adapt to the browser window using `window.innerWidth` and `window.innerHeight`, with a fixed circle radius of 30 pixels.
