{"version":"1.0","type":"rich","title":"MouseFollower","description":"A single black circle tracks the mouse cursor across a full-window SVG canvas. The visualization demonstrates real-time interaction using React state and event handling. The circle's center coordinates update on every mouse movement via the `onMouseMove` event, with `useState` and `useCallback` managing position updates. Rendered with ReactDOM and SVG elements, the example shows a minimal interactive data display where the circle directly mirrors user input.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
