{"version":"1.0","type":"rich","title":"Mouse Follower","description":"A yellow circle follows the mouse cursor across a blank SVG canvas, updating its position in real time as the user moves the pointer. Built with React hooks, the app tracks mouse coordinates through the `onMouseMove` handler and stores them in state via `useState`. The circle re-renders at the new location on every movement event, demonstrating a simple interactive visualization that combines React's declarative rendering with D3's SVG utilities.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
