{"version":"1.0","type":"rich","title":"Mouse Follow","description":"A circle inside an SVG follows the mouse's movement across the viewport in real time. The app initializes the circle at the center of a 960-by-500 coordinate space, then updates its position on every mousemove event. React’s `useState` and `useCallback` hooks manage the mouse coordinates, which are passed to the circle’s `cx` and `cy` attributes. The example renders using ReactDOM and React 16.13.1, with the SVG’s `onMouseMove` handler triggering the state update.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
