{"version":"1.0","type":"rich","title":"Mouse follower","description":"A cursor-following smiley face tracks the mouse across an SVG canvas in this React application. The code uses React's `useState` hook to store mouse coordinates and a `useCallback` handler to update them on `onMouseMove` events. Each mouse movement re-renders a single yellow circle with black stroke, whose center position is bound to the current mouse coordinates. The example demonstrates real-time interaction between browser pointer events and declarative SVG rendering through React's state management.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a0e90828a20049199726b1d79d0034c4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
