A real-time web application that tracks and displays user locations on an interactive map. Built with Node.js, Socket.io, and Leaflet, this location tracker allows multiple users to share their geographic position instantly.

• Real-Time Tracking: Instantly updates user locations on the map as they move.
• Multi-User Support: Visualize multiple users simultaneously on the same map interface.
• Interactive Maps: Powered by Leaflet for smooth zooming and panning.
• Automatic Disconnection: Removes users from the map when they disconnect.
