{"version":"1.0","type":"rich","title":"Mouse Follower","description":"A black circle follows the mouse cursor across a blank SVG canvas, centering itself on the pointer's exact coordinates. The visualization demonstrates a simple interactive loop using React's `useState` and `useCallback` hooks to track `clientX` and `clientY` positions from a mouse move event, while D3 v6 handles SVG rendering. The circle has a fixed radius of 30 pixels and starts at the canvas center before responding to user movement.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
