Interaction with React
✓ Published1🌍 Public
A smiley face drawn as a React SVG circle follows the cursor around the screen. The application tracks mouse position through React state, updating on every `onMouseMove` event on the SVG element. App state changes trigger a re-render, moving the circle to the new coordinates. The example demonstrates binding React’s `useState` and `useCallback` hooks to interactive SVG rendering in a full-window viewport.
