{"version":"1.0","type":"rich","title":"Mouse Follower","description":"A circle tracks the mouse cursor across a full-window SVG canvas, responding to every pointer movement in real time. React state updates the circle’s center coordinates on each `mousemove` event, using the `useState` hook and a `useCallback` handler. The visualization renders with React 16.9 and SVG, with no external data source or animation library—only direct event-driven position updates.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/31300e032a99438faf623df288a250d2?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
