{"version":"1.0","type":"rich","title":"Mouse Follower","description":"A React application renders a single SVG circle that follows the mouse cursor across the full browser window. The component tracks pointer coordinates via React's `useState` and `useCallback` hooks, updating the circle's `cx` and `cy` attributes on every `onMouseMove` event. The viewport dimensions come from `window.innerWidth` and `window.innerHeight`, with the circle initially centered before the first mouse movement. The example demonstrates reactive state-driven SVG updates in a React 16.9 environment.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f298dad551a548a7b127345d30b4b6c6?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
