Comment (by karsten):

 Hmm, I had some trouble fetching that .csv file.  The server seems quite
 overloaded, and the downloaded file was partially corrupt.  But I think I
 got the overall picture.

 However, I noticed that you didn't implement the wide-to-long suggestion I
 mentioned a few months ago on [https://lists.torproject.org/pipermail
 /metrics-team/2016-February/000076.html metrics-team@], and I think that
 would make the graphing code somewhat easier.  How likely is it that
 you'll find the time to work on that issue?

 But we probably shouldn't block on that for putting stuff on Tor Metrics.
 How's this approach:

  - We start by adding two new "link" pages to your
 [https://nymity.ch/sybilhunting/churn-values/slide_2016-01.html churn] and
 [https://nymity.ch/sybilhunting/uptime-visualisation/slide_2014-01.html
 uptime] visualizations.  Can you send me text similar to the
 [https://gitweb.torproject.org/metrics-
 web.git/tree/website/etc/metrics.json#n532 "oxford-anonymous-internet"
 link page] but for these two new link pages?  We'll need this text anyway
 even when we take the next steps below.

  - We add a new page type to Metrics called "gallery" which displays image
 files from a local directory directly on the Tor Metrics site.  We need
 this type anyway for the uptime visualizations even when we replace the
 churn visualizations by something more interactive below.  We'd produce
 these images exactly how you're currently producing them on your server
 but on the metrics server.  Once we deploy this gallery pages, we'll
 replace the corresponding link pages, though we'd keep the URLs unchanged.

  - We write some R/ggplot2 code to make the churn visualizations somewhat
 more interactive by letting users select start and end date, flag type,
 and displayed metric (absolute numbers, fractions, etc.).
