{"version":"1.0","type":"rich","title":"Mouse Follower","description":"A full-screen SVG circle follows the mouse cursor in real time, with its center tied directly to the pointer’s clientX and clientY coordinates. Built with React, the example uses the `useState` and `useCallback` hooks to track mouse position and update the circle’s `cx` and `cy` attributes on every move. Rendering is handled via ReactDOM to an SVG element that spans the entire browser window, with no explicit data source beyond user input.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
