{"version":"1.0","type":"rich","title":"Mouse Follower","description":"A single black circle tracks the mouse across an SVG canvas, smoothly following the cursor’s exact screen coordinates in real time. The React component uses the `useState` hook to store the mouse position and a `useCallback` handler for `onMouseMove` events, updating the circle’s `cx` and `cy` attributes. Rendering is handled by ReactDOM, with D3’s `arc` import available but unused. The minimal interaction demonstrates how React state and SVG event binding can create responsive pointer-driven visuals.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/89092eeda26342328e1cb14e86aba3fd?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
