{"version":"1.0","type":"rich","title":"Mouse Follower","description":"A circle follows the mouse cursor across the full browser window, changing its radius randomly with each movement. Built with React, the app tracks mouse coordinates via an SVG `onMouseMove` handler and updates the circle’s `cx`, `cy`, and `r` attributes through React state. The `useState` and `useCallback` hooks manage the position and re-render, while the radius is generated by a custom `randomIntFromInterval` function, resulting in a dynamic, size-shifting target.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8eb4b3c47bd24831996a758430338980?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
