{"version":"1.0","type":"rich","title":"Mouse Follower","description":"A yellow circle follows the mouse cursor across an SVG canvas, updating its position in real time with each pointer movement. The visualization uses React hooks (`useState` and `useCallback`) to manage mouse coordinates and trigger re-renders, while React’s synthetic `onMouseMove` event captures the cursor’s clientX and clientY values. Rendered as an SVG circle, the example demonstrates a simple interactive pattern leveraging D3’s presence only for the script tag, with React handling all state and rendering logic.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
