{"version":"1.0","type":"rich","title":"mouse follower","description":"A circle follows the mouse pointer across an SVG canvas, updating its center position in real time to mirror the cursor's location. The React component uses a `useState` hook to track mouse coordinates and a `useCallback` handler on the SVG element's `onMouseMove` event. The circle is rendered with a D3.js arc path, though the simple shape relies on React's declarative SVG attributes for positioning, with no external data source.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
