{"version":"1.0","type":"rich","title":"mouse follower","description":"A smiling face, drawn as a single SVG circle, follows the mouse cursor across a 960 by 500 canvas. The React application tracks pointer movement via the `onMouseMove` event, updating the circle's center coordinates in its state. The reusable `useCallback` hook optimizes the event handler, and ReactDOM renders the interactive graphic inside the `#root` div. The example demonstrates real-time state-driven SVG redrawing using React 16.9.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2b4df42d380c46618135359de2ddf585?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
