{"version":"1.0","type":"rich","title":"Mouse Follower","description":"A circle follows the mouse cursor across an SVG canvas in this React visualization. The app tracks the pointer's `clientX` and `clientY` coordinates on every `mousemove` event, storing them in state and updating the circle's `cx` and `cy` attributes accordingly. React 16.9 handles the component state with the `useState` and `useCallback` hooks, while `ReactDOM.render` mounts the application to the DOM. The rendering uses React's JSX syntax to produce the SVG output.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
