{"version":"1.0","type":"rich","title":"Mouse follower","description":"A single black circle follows the mouse cursor across a blank SVG canvas, updating its position in real time. The React app tracks pointer coordinates through an `onMouseMove` event handler and stores them in state with `useState`, then re-renders the circle using the `clientX` and `clientY` values. The example demonstrates a basic interactive pattern using React’s `useCallback` and ReactDOM, with SVG circle elements for rendering.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6a8fce1c489f44d586bde7431209972c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
