{"version":"1.0","type":"rich","title":"Mouse Follower","description":"A black circle follows the mouse cursor as it moves across a full-screen SVG canvas. The visualization updates the circle's position in real time using React's `useState` and `useCallback` hooks with an `onMouseMove` event handler. The code combines React 16.9 with D3.js v7, rendering solely through SVG elements without any data source, demonstrating interactive state-driven graphics.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/22bc7d55073243ab8c69b594b2d1d900?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
