{"version":"1.0","type":"rich","title":"Mouse Follower","description":"A single black circle follows the mouse cursor across a blank SVG canvas. The circle’s position updates in response to mouse movement via a React state hook (`useState`) and an `onMouseMove` event handler. The example uses React 16.9 for component rendering and event handling, with the SVG element created directly in JSX. No external data or D3 functions are used; only React’s state management drives the dynamic repositioning.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c31cfc7b17774fc9acbd39d7fc2f9736?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
