{"version":"1.0","type":"rich","title":"Mouse Follower","description":"A yellow circle follows the mouse across a blank SVG canvas, responding instantly to pointer movement within the viewport. The visualization uses React state and the `useCallback` hook to track client coordinates, updating the circle's `cx` and `cy` attributes through React's declarative rendering. The page loads React 17 and D3 v7 from a CDN, though the interaction relies solely on event handling rather than D3-specific APIs. The minimalist setup with a full-screen, overflow-hidden body ensures uninterrupted tracking.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0bf308f9bd5341678969fd8f30cd1063?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
