{"version":"1.0","type":"rich","title":"Mouse Moving","description":"A full-screen SVG scene tracks the mouse cursor with a single circle that updates its center coordinates in real time. Built with React’s `useState` and `useCallback`, the `handleMouseMove` event captures `clientX` and `clientY` from the SVG’s `onMouseMove` listener, then re-renders the circle’s `cx` and `cy` properties. React 16.9 and D3 v5 are loaded via CDN, with the circle’s radius fixed at 30 pixels. The visualization demonstrates declarative state-driven rendering without any data source or animation.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/48834fa9b8114f87b37fddfa1507eb8b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
