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.

Mouse Follower

A single circle tracks the mouse as it moves across a full-screen SVG canvas, with its position updating in real time to mirror the cursor’s coordinates. Built with React and ReactDOM, the app uses the `useState` hook to store the mouse position and the `useCallback` hook to handle the `onMouseMove` event on the SVG element. The viewport dimensions come from `window.innerWidth` and `window.innerHeight`, and the circle is rendered as an SVG `<circle>` element with a fixed radius of 30 pixels.

Mouse Follower

A circle follows the mouse cursor across an SVG canvas, updating its position in real time as the pointer moves. Built with React, the app uses the `useState` hook to store the mouse coordinates and a `useCallback` handler triggered by the SVG's `onMouseMove` event. The circle is rendered as an SVG `<circle>` element with a fixed radius of 30 pixels. The viewport is set to 960 by 500 pixels, and the initial position is centered before any mouse movement occurs.

Mouse Follower

A circle tracks the user’s cursor within a 960×500 SVG canvas, updating its center position in real time as the mouse moves. Built with React, the app uses the `useState` hook to store mouse coordinates and a `useCallback` handler on the SVG’s `onMouseMove` event. The rendering is done entirely with SVG elements, and the circle’s radius is fixed at 30 pixels.

Mouse Follower

A full-screen React SVG component renders a single circle that follows the mouse as it moves. The app tracks mouse coordinates using React's `useState` hook and handles `onMouseMove` events on the SVG element, updating the circle's `cx` and `cy` attributes in real time. The initial position is centered in the window, and the circle radius is fixed at 30 pixels. No external data source is used; the visualization simply demonstrates interactive state-driven rendering with React and SVG.

Mouse Follower

A circle rendered as an SVG element follows the mouse cursor in real time. The React application tracks the pointer’s coordinates through the `onMouseMove` event on the SVG canvas and updates the circle’s `cx` and `cy` attributes accordingly. The visualization uses React’s `useState` hook for state management and `useCallback` for the event handler, with the SVG width and height fixed at 960 by 500 pixels.

Mouse Follower

A circle rendered in SVG follows the mouse cursor across a 960 by 500 viewport. Built with React and ReactDOM, it tracks pointer movement via the `onMouseMove` event handler, storing the cursor's `clientX` and `clientY` coordinates in state using the `useState` hook. The `useCallback` hook optimizes the handler, and the circle's `cx` and `cy` attributes update reactively to reposition the circle at the current mouse location.

Mouse Follower

A full-screen SVG circle tracks the mouse in real time. It demonstrates React state management and event handling by updating the circle’s coordinates on every pointer movement. The application uses React’s `useState` and `useCallback` hooks within a functional component, rendering a single `<circle>` element inside an `<svg>` that covers the viewport. The `onMouseMove` event triggers a state update with the cursor’s `clientX` and `clientY` positions, causing React to re-render the circle at the new location.

Mouse Follower

A React and SVG visualization that tracks the mouse cursor with a single circle. The circle's position updates live as the user moves over a 960 by 500 SVG canvas, using React's `useState` and `useCallback` hooks to manage the cursor coordinates and an `onMouseMove` event handler. The circle is rendered as an SVG `<circle>` element with a fixed radius of 30 pixels, while the initial position is centered on the screen.
