{"version":"1.0","type":"rich","title":"Mouse Follower","description":"A yellow circle follows the mouse cursor across a full-screen SVG canvas. The visualization is built with React hooks, using `useState` to track the cursor position and `useCallback` for the mouse-move event handler. The D3 library is available but not actively used; instead, React's rendering updates the circle’s `cx` and `cy` attributes in real time. The example demonstrates simple interactive state management within a React-D3 integration.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
