{"version":"1.0","type":"rich","title":"Mouse Follower","description":"A single yellow circle follows the mouse cursor across the full browser window, updating its position in real time. The visualization uses React hooks, specifically `useState` to track mouse coordinates and `useCallback` to optimize the event handler, with the circle rendered as an SVG `<circle>` element. Mouse movement triggers the `onMouseMove` event, and the React re-renders the circle at the new `clientX` and `clientY` positions on each move.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/34ab24a753f04521972631a7296fb3d8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
