{"version":"1.0","type":"rich","title":"Cursor Follower","description":"A dark red circle tracks the mouse cursor across a full-screen SVG canvas, updating its position in real time. React hooks (`useState` and `useCallback`) manage the cursor coordinates and handle mouse-move events. The circle’s center is offset upward by its radius, and the viewport size is derived from `window.innerWidth` and `window.innerHeight`. The example renders a single SVG circle with JavaScript and React.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4a19ec0cdc3e49ce89d08ffd0da318df?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
