This example shows a circle that continuously follows the mouse cursor across a full-window SVG canvas. Built with React, it tracks the cursor’s `clientX` and `clientY` coordinates through an `onMouseMove` event handler, storing the position in state via `useState` and updating the circle’s `cx` and `cy` attributes accordingly. The `useCallback` hook optimizes the event handler, and the component renders a single SVG `<circle>` element without any data source.

Mouse Follower

This example shows a single circle that follows the mouse cursor across the full browser window. The circle’s position updates live through React state, using the `clientX` and `clientY` values from the `onMouseMove` event on an SVG element. The code renders the circle as an SVG `<circle>` with React 16.9, and the state hook `useState` manages the cursor coordinates. The visualization demonstrates a simple interactive mapping between pointer movement and SVG shape placement.

Mouse Follower

A single circle follows the mouse cursor across a full-screen SVG canvas. Built with React and SVG, the example uses the `useState` and `useCallback` hooks to track `clientX` and `clientY` coordinates from the SVG element's `onMouseMove` event, updating the circle's `cx` and `cy` attributes in real time. The circle starts at the center of the viewport and moves smoothly with pointer input.

Mouse Follower

A circle follows the mouse cursor across a full-window SVG canvas. Built with React, the app tracks pointer coordinates through an SVG `onMouseMove` handler, stores them in state with the `useState` hook, and updates the circle's `cx` and `cy` attributes on every move. The `useCallback` hook memoizes the event handler for efficiency, while the initial mouse position is centered on the screen. Rendering uses ReactDOM to mount the component into the page.

Mouse Follower

This example shows a single circle that follows the mouse cursor across the full browser window. The circle’s position updates in real time as the user moves the pointer over an SVG canvas. Built with React (version 16.9.0) and ReactDOM, the component uses the `useState` hook to store the mouse coordinates and the `useCallback` hook to handle `mousemove` events, retrieving `clientX` and `clientY` from the event object. The SVG is sized to `window.innerWidth` and `window.innerHeight`, with the circle’s `cx` and `cy` attributes bound to the current mouse position.

Mouse Follower

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.

Mouse Follower

A circle follows the mouse cursor across an SVG canvas. The example demonstrates state management in React, using the `useState` hook to track cursor coordinates and the `useCallback` hook to optimize the mouse move event handler. React renders the circle's position dynamically with a 20-pixel radius, starting at the center of a 960 by 500 viewport. The code uses React 16.9 and ReactDOM to render the SVG element, updating the circle's `cx` and `cy` attributes on every `mousemove` event.

Mouse Follower

A circle follows the mouse cursor across a full-screen SVG canvas, updating its position in real time in response to pointer movement. The React app tracks the mouse coordinates via the `onMouseMove` event handler and stores them in state with `useState`, while `useCallback` memoizes the handler for efficiency. The circle’s center is rendered at the cursor’s `clientX` and `clientY` coordinates, with a fixed radius of 30 pixels, using React and ReactDOM to manage the SVG output.

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.
