{"version":"1.0","type":"rich","title":"Mouse Follower","description":"A smiley face rendered as an SVG circle follows the mouse cursor across the full window. React state tracks the pointer position via an `onMouseMove` handler, and the circle’s `cx` and `cy` attributes update accordingly. The implementation uses React 16.9 with hooks (`useState`, `useCallback`) and renders directly to SVG, with the viewport size set from `window.innerWidth` and `window.innerHeight`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ad7549ed2bce4fb3af410cd7e7c0d28a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
