Comment:

 Okay, I finished a first [https://gitweb.torproject.org/user/karsten
 /metrics-
 web.git/commit/?h=task-32135&id=93f2500cabf22fdf03d109bb7855445b18afd62d
 patch] that processes BridgeDB metrics once per day to produce a .csv file
 and that adds two graphs to Tor Metrics. Can you please take a look at
 that patch, not regarding the Java/R code, but regarding user-facing
 documentation of the two new graphs? In particular, please take a look at
 the `TODO`s in that patch. (irl, I'll ask you to review a revised branch
 for the code portions once the documentation parts are all set.)

 By the way, while reading your code, I found that you're only looking at
 BridgeDB metrics files in CollecTor's `recent/` directory. There's
 currently a (minor) bug in CollecTor where we never remove files from that
 directory. I'm going to fix that at some point, and then your script will
 only provide the latest three files. A possible fix would be to also
 process files in CollecTor's `archive/` directory. Not sure how much of an
 issue that is when these graphs exist on Tor Metrics, but I thought I
 should let you know.
