Fork of Smiley Face Part II
✓ Published0🌍 Public
A single yellow circle follows the mouse cursor across a full-window SVG canvas. The circle is drawn with fixed radius 30, and its position updates in response to mouse movement events. The React application uses `useState` and `useCallback` to track cursor coordinates and condition the circle's `cx` and `cy` attributes. The code creates an interactive SVG visualization where a simple shape directly mirrors the pointer's location.
