This example shows a yellow circle that follows the mouse cursor across the full browser window. It uses React's `useState` and `useCallback` to track mouse coordinates, which are passed to an SVG circle's `cx` and `cy` attributes. The circle has a fixed radius of 30 pixels and is rendered on an SVG canvas sized to the window's dimensions. The `onMouseMove` event handler updates the circle's position in real time, and the SVG is rendered through ReactDOM.

Mouse Follower

A yellow circle follows the mouse cursor across a full-window SVG canvas. Built with React and rendered using SVG, the application tracks pointer movements through an `onMouseMove` event handler, updating the circle's `cx` and `cy` coordinates in real time. The code uses React's `useState` and `useCallback` hooks, with the SVG viewport sized to the browser's `window.innerWidth` and `window.innerHeight`.

Mouse Follower

A circle follows the mouse cursor across a yellow-bordered SVG canvas. The React application tracks the pointer's client coordinates and repositions a fixed-radius circle at that location. Using React's `useState` and `useCallback`, it updates the circle's `cx` and `cy` attributes on every mouse move. The `onMouseMove` handler on the SVG element captures the position, and ReactDOM renders the updated circle at the new coordinates.

Mouse Follower

A yellow circle follows the mouse cursor across a full-window SVG canvas built with React. The component tracks pointer coordinates via the `onMouseMove` event handler and updates state with `useState`, re-rendering the circle’s `cx` and `cy` attributes on each move. Rendering is handled by ReactDOM and React 16.9, with the SVG viewport sized to `window.innerWidth` and `window.innerHeight`. No external data source is used; the visualization purely demonstrates interactive state-driven positioning.

Mouse Follower

A yellow circle follows the mouse cursor across a blank SVG canvas. The example demonstrates mouse tracking in React by updating the circle’s center coordinates on every pointer move. It uses React’s `useState` and `useCallback` hooks, with the `onMouseMove` event handler reading `clientX` and `clientY` from the event object to re-render the circle. The SVG is rendered via ReactDOM, and the initial circle position is centered within a 960×500 viewport.

Mouse Follower

A yellow circle follows the mouse cursor across a full-window SVG canvas. The circle’s position updates in real time to match the cursor’s coordinates, offset slightly down and right. The visualization uses React with the `useState` hook to track mouse movement and re-render the SVG circle on each event. The `onMouseMove` event handler captures `clientX` and `clientY` from the JavaScript `MouseEvent`, and the circle is drawn with a fixed radius of 30 pixels and a fill color of `#fcd947`.

Mouse Follower

A yellow circle rendered in SVG follows the mouse as it moves across the full browser window. The React component tracks pointer coordinates through an `onMouseMove` handler on the SVG element, updating state with React hooks `useState` and `useCallback`. The circle’s center is set from the current `clientX` and `clientY` values, with an initial position at the viewport’s midpoint.

A yellow circle with a black outline follows the mouse cursor across a 960-by-500 SVG canvas. The example uses React's `useState` and a callback to track the cursor's `clientX` and `clientY` coordinates, updating the circle's `cx` and `cy` attributes directly on mouse movement. This demonstrates interactive SVG rendering within a React component, with the circle’s position driven entirely by user input.

Mouse Follower

A yellow circle follows the mouse cursor across a fixed 960 by 500 SVG canvas. The example demonstrates real-time mouse tracking with React 16.9.0, using the `useState` and `useCallback` hooks to manage cursor coordinates. The `onMouseMove` event on the SVG element updates the circle’s `cx` and `cy` attributes, causing it to smoothly track the pointer. The code renders a single SVG circle with no data source, purely illustrating interactive state updates in a React-driven visualization.
