{"version":"1.0","type":"rich","title":"Mouse Follower","description":"A full-screen SVG circle tracks the mouse in real time. It demonstrates React state management and event handling by updating the circle’s coordinates on every pointer movement. The application uses React’s `useState` and `useCallback` hooks within a functional component, rendering a single `<circle>` element inside an `<svg>` that covers the viewport. The `onMouseMove` event triggers a state update with the cursor’s `clientX` and `clientY` positions, causing React to re-render the circle at the new location.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d38036373a4b497ebd40672976a9f933?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
