{"version":"1.0","type":"rich","title":"Fork of React Starter","description":"This example demonstrates scroll-driven scaling: a sticky sky-blue box grows from 50% to 100% scale as the page scrolls through a 200vh wrapper. The App component tracks scroll progress via a `window.scrollY` event listener, computes a percentage from the scroll position relative to the wrapper’s total height, and applies the result as an inline `transform: scale()` style. It uses React’s `useState`, `useEffect`, `useRef`, and `useCallback` hooks, with rendering handled by `createRoot`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4f7afa0fa75f4ce1ab7d07e6aa6ac315?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
