{"version":"1.0","type":"rich","title":"Mouse Follower","description":"A circle follows the mouse cursor across a full-window SVG canvas. Built with React, the app tracks pointer coordinates through an SVG `onMouseMove` handler, stores them in state with the `useState` hook, and updates the circle's `cx` and `cy` attributes on every move. The `useCallback` hook memoizes the event handler for efficiency, while the initial mouse position is centered on the screen. Rendering uses ReactDOM to mount the component into the page.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
