Show HN: Explore Tor relays on a world map over time

Hey HN,

Together with a friend from university, I build a world map to show the distribution of public Tor relays. The historical state of the network can be viewed for any day between October 2007 and today: https://tormap.org/

We look up the current geolocation of IP addresses collected from the official Tor project archives: https://metrics.torproject.org/collector.html

Over time, the project has grown to support more features such as extensive filtering, searching, visualisation of different groupings, and looking up details of individual relays.

Source code for both the frontend and backend is also available here: https://github.com/TorMap/tormap

We hope you find our little web app useful and would love to hear your feedback.

Cheers, Julius
