Mouse Follower

Mouse Follower

A yellow circle follows the mouse cursor across an SVG canvas. Built with React, the app tracks cursor coordinates via the `onMouseMove` event and stores them in state using the `useState` hook. The `useCallback` hook optimizes the event handler, and `ReactDOM.render` mounts the component. The SVG’s circle element updates its `cx` and `cy` attributes to match the current mouse position, creating a direct, real-time visual response.

A yellow circle follows the mouse cursor across a 960×500 SVG canvas, updating its position in real time through React state. The app uses `useState` to store the current mouse coordinates and `useCallback` to handle `mousemove` events, with the circle’s `cx` and `cy` attributes bound to that state. Rendered via ReactDOM and React 16.9, the visualization demonstrates reactive SVG updates without any external data source.

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.

A yellow circle follows the mouse cursor across a full-screen SVG canvas. The visualization demonstrates a simple interactive state update in React, where the circle’s position mirrors the cursor’s coordinates in real time. The component uses React’s `useState` hook to track the mouse position and `useCallback` to handle the `onMouseMove` event, updating the circle’s `cx` and `cy` attributes. The SVG rendering is driven entirely by React’s declarative updates, with no additional data source or animation library involved.

A yellow circle follows the mouse cursor across an SVG canvas in this interactive React example. The visualization tracks pointer position using React's `useState` hook and updates the circle's center coordinates through an `onMouseMove` event handler on the SVG element. The `useCallback` hook optimizes the event handler, which reads `clientX` and `clientY` from the mouse event and stores them in state. React re-renders the circle at the new position, demonstrating a simple state-driven interaction pattern in a React and SVG environment.

A yellow circle follows the mouse cursor across a 960-by-500 SVG canvas. Built with React and ReactDOM, the app tracks pointer coordinates via an `onMouseMove` handler on the SVG element, storing them in state with `useState` and updating them through `useCallback`. Each move re-renders the circle's `cx` and `cy` attributes, creating a direct, responsive visual link between pointer position and the rendered shape.

A React component renders a yellow circle that follows the mouse cursor within an SVG canvas. The circle’s position is updated via React state, driven by the SVG’s `onMouseMove` event handler, which captures `clientX` and `clientY` coordinates. The example demonstrates interactive SVG rendering with React hooks (`useState`, `useCallback`) and `ReactDOM.render`. The circle starts centered in the 960×500 viewport and moves responsively with the pointer.

A yellow circle follows the mouse cursor across an SVG canvas, updating its position in real time. The example demonstrates React state management and event handling: the `App` component tracks mouse coordinates via the `onMouseMove` event and renders a circle centered on those coordinates. It uses `useState` to store the cursor position and `useCallback` for the event handler, with React and ReactDOM rendering the interactive SVG element.
