Comment (by karsten):

 Thanks for your comments! A couple questions before I continue putting
 your suggestions in:

  - The change from "transport" to "bridge type" is a tricky one. We're
 using "transport" where you'd use "bridge type" for other graphs, like
 [https://metrics.torproject.org/userstats-bridge-transport.html this one].
 I guess part of the rationale was that even with the default OR protocol,
 messages are being ''transported'' between client and bridge, just not
 using one of the ''pluggable'' transports but using the built-in one. But
 we're using this term for almost a decade now, so it's well possible that
 it's merely the result of me convincing myself that it must be a good
 idea. That being said, part of me would prefer keeping the "transport"
 term here. However, if you think this is too confusing, let's consider
 making this change. What do you prefer?

  - "Distribution" vs. "distribution method" is another case like this.
 We're not using this term on Tor Metrics yet. But we should be sure to
 pick the term that is most common in the Tor universe. I vaguely recall
 the term "distributor" from when I wrote the BridgeDB spec, but that term
 might be too technical for this purpose. Anyway, what's the term you would
 want us to use here?

  - Regarding your suggestions to graph titles, keep in mind that short
 titles work better on the website (and on graph images) than long ones. At
 the same time they need to be meaningful in the context of all other
 graphs/tables on the Metrics website.

  - You wrote in several places that "unsuccessful requests (e.g., invalid
 emails or incorrect CAPTCHAs) are not included in these numbers." But is
 this true in your code and in mine? What would I have to do to filter out
 these requests?

  - The "unbin" part is about the `-bin_size/2`, yes. I already made that
 change in the code locally, and we should document it.

 Would you want to provide your changes as a Git-formatted patch (or Git
 branch) based on mine? That would make it a bit easier for me to include
 your changes (and harder to miss out good suggestions).

 I'll work more on this tomorrow. Thanks!
