 the blog post is good enough to run it once for a blog post, but it needs
 more work for being run periodically. Here are a few issues:

 using the very same geoip file in a graph covering years of data. We'll
 need to find a way for automating updating geoip files. And we need to
 define which geoip file we're using for any given consensus. That last
 sentence alone is far from being trivial if we want to ensure that two
 people have a chance to independently produce the same graph.

 Aren't these the same GeoIP files as the ones used for Tor metrics
 currently?

 or we'll be sad whenever the server reboots in the wrong moment. And we
 want the database schema to scale for the next five years.

 Nonetheless do you think that these issues can be created as separate sub-
 tickets?
