{"version":"1.0","type":"rich","title":"Mouse Follower","description":"A single circle in an SVG viewport tracks the user's mouse in real time, following its position across the full screen. Built with React, the app uses the `useState` hook to store the current mouse coordinates and the `useCallback` hook to update them via the SVG `onMouseMove` event handler. The circle’s `cx` and `cy` attributes are bound directly to this state, causing a re-render on every pointer movement. The rendering approach is purely declarative, with the circle’s radius fixed at 30 pixels.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/135bdfbfb7ea4c4ca1efb8da5fb6f280?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
