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