{"version":"1.0","type":"rich","title":"Mouse Tracking","description":"A single circle tracks the mouse cursor in real time across a full-screen SVG canvas. Built with React 18, the app uses the `useState` hook to store cursor coordinates from the `onMouseMove` event on a div catcher, then passes those coordinates to an SVG circle’s `cx` and `cy` attributes for immediate repositioning. The `useCallback` hook memoizes the event handler for efficiency. ReactDOM renders the component into the page’s root element.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/db2feb68e63144d1a6561a87fd63c869?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
