 When we added graphs on onion services back in
 [https://gitweb.torproject.org/metrics-
 web.git/commit/?id=4ea56ba80d54d8a34a994181ecb715c544654162 March 2015],
 we also included the [https://metrics.torproject.org/hidserv-frac-
 reporting.html "Fraction of relays reporting onion-service statistics"
 graph].

 Back then, this graph was somewhat useful for pro users, to see how onion-
 service statistics deployment proceeded over time and to assess how much
 we could trust the overall numbers. However, since fractions went up to
 50% in 2016 or even 75% in 2017, this graph has become less relevant.

 Also, when we added this graph in 2015 we still had an "advanced/pro"
 category of graphs that were not displayed by default. We don't have that
 distinction anymore and simply throw everything we have at our users.

 I suggest we remove this graph now from Tor Metrics. It costs maintenance
 effort, and it distracts our users from the more important graphs.

 We could (should?) even keep providing the data by including a `frac`
 column in the CSV files linked from the other two onion-service graphs.
 That's how we do this with the user number graphs. If somebody wants to
 graph fractions of reported statistics, they can easily do that themselves
 using their favorite graphing tool.

 Thoughts? Are there any good reasons to keep this graph?
