A circle follows the mouse cursor across an SVG canvas, responding in real time to pointer movement. The example demonstrates React state management with a `useState` hook and `useCallback` for the mouse event handler, while ReactDOM renders the SVG circle at the updated coordinates. It uses React 16.9.0 and renders entirely via SVG elements, with the initial circle positioned at the center of a 960×500 viewport.

This example visualizes real-time mouse tracking by rendering a circle that follows the cursor across an SVG canvas. It shows how React state management updates visual elements in response to user input events. The code uses React’s `useState` and `useCallback` hooks to track and update the mouse position via the `onMouseMove` event handler, and renders the circle as an SVG element with dynamic `cx` and `cy` attributes. The implementation relies on React 16.9 and ReactDOM to mount the component, with no additional data sources.

This React and SVG example displays a single circle that follows the mouse cursor across a 960 by 500 canvas. The circle’s position updates in response to mouse movement events, initially centered on the screen. The application uses React’s `useState` and `useCallback` hooks to manage the cursor coordinates, and ReactDOM renders the SVG element with an `onMouseMove` handler. The visualization demonstrates real-time interaction by directly mapping the cursor’s client coordinates to the circle’s `cx` and `cy` attributes.

A gray circle follows the mouse cursor across a blank SVG canvas, updating its position with every pointer movement. The React component tracks the cursor’s clientX and clientY coordinates via the onMouseMove event, storing them in state and re-rendering the circle’s cx and cy attributes. The visualization uses React 16.9’s useState and useCallback hooks inside a functional component, rendering the shape through ReactDOM into an SVG element sized 960 by 500 pixels.

A circle follows the mouse cursor across an SVG canvas, recentering itself as the pointer moves. The example uses React hooks `useState` and `useCallback` to manage the mouse position and update the circle’s `cx` and `cy` attributes via the SVG `onMouseMove` event. Rendering is handled by React DOM, with the visualization limited to a static circle whose radius remains constant.

A circle follows the mouse cursor across a 960 by 500 SVG canvas, updating its position in real time as the pointer moves. The React app uses the `useState` hook to store the current mouse coordinates and the `useCallback` hook to handle the `onMouseMove` event on the SVG element. The rendered circle’s center is bound to the state, and ReactDOM re-renders the element on every mouse movement. The visualization relies on React 16.9.0 and SVG for its rendering.

A circle follows the mouse cursor across an SVG canvas, updating its position in real time. The React application uses a `useState` hook to track the cursor’s coordinates, and a `useCallback` event handler updates the circle’s `cx` and `cy` attributes on every mouse movement. Rendered with ReactDOM into an SVG element, the example relies on the `onMouseMove` event to capture pointer position, with the circle’s radius fixed at 30 pixels.

A circle follows the mouse cursor across a 960 by 500 SVG canvas, updating its position in real time. Built with React, the app tracks `onMouseMove` events to store the cursor’s coordinates in state and re-renders a single `<circle>` element with the new `cx` and `cy` values. The example uses React’s `useState` and `useCallback` hooks alongside ReactDOM, with visual output rendered entirely as SVG.
