Comment(by karsten):

 Roger and I today talked about the list of possible bandwidth data to be
 provided by Onionoo.  We came up with these three new graphs:

  1. Fraction of advertised bandwidth in the network (based on c above).
 This metric is similar to the current consensus weights which are based on
 measured bandwidths, but for the case that we'd return to self-reported
 bandwidths.

  2. Consensus weight fraction as compared to all other relays in the
 network (same as d above).

  3. Approximate probability for a relay to be selected by clients (based
 on e above).  This metric is based on consensus weights and the Exit and
 Guard flags.  I'm not entirely clear yet how this metric would be
 calculated.  Maybe it's something like 1/3 * (P(selected as guard) +
 P(selected as middle node) + P(selected as exit)).

 Maybe we should have some sample graphs for a few relays first and decide
 that these are the graphs we want Onionoo/Atlas to provide.

 Arturo and I also talked about improving Atlas' interface to display
 different types of bandwidth graphs.  Instead of having six graphs for
 different time periods of the same data, we could have a single graph with
 six buttons to switch between the various intervals.  That also allows us
 to add new bandwidth graphs.
