- Introduced latitude and longitude fields in the IP data structure to support geographic information.
- Updated the API documentation to reflect the inclusion of geographic coordinates in the unique IPs endpoint.
- Enhanced the UI to display a map of connections using Leaflet, providing a visual representation of IP locations based on the new geographic data.
- Improved the handling of GeoIP data to ensure accurate mapping and user experience when GeoIP is enabled.
