{"version":"1.0","type":"rich","title":"Mouse Follower","description":"A circle follows the mouse cursor across an SVG canvas, showing real-time pointer tracking in React. The visualization uses React hooks—`useState` to store the mouse position and `useCallback` for an `onMouseMove` event handler that updates the circle’s `cx` and `cy` attributes. It renders via ReactDOM into the DOM and depends on React 16.9's production UMD builds, with the SVG circle initially centered on a 960×500 viewport. The code directly maps `clientX` and `clientY` from the event to the circle’s coordinates.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
