{"version":"1.0","type":"rich","title":"Mouse Follower","description":"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.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
