Fork of Smiley Face Part II
✓ Published0🌍 Public
A purple circle follows the mouse cursor across a blank SVG canvas, updating its position in real time with each pointer movement. Built with React and ReactDOM, the interactive graphic uses the `useState` and `useCallback` hooks to track and update mouse coordinates via an `onMouseMove` handler on the root SVG element, rendering the circle at the current pointer location.
