{"version":"1.0","type":"rich","title":"Mouse Follower And Resizer","description":"A green circle follows the mouse cursor across a full-screen SVG canvas. Clicking the mouse grows the circle’s radius by 10 pixels, while shift-clicking shrinks it, with a minimum size of zero. Built with React components and event handlers, the code uses React’s `useState` and `useCallback` hooks to track mouse position and radius, rendering the circle via SVG elements and updating on each mouse event.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e04ef030c531421fb1c97478f2f00520?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
