Comment:

 It seems the graph was at least somewhat useful, right?  Moving forward by
 making this an Onionoo task to provide the required data for Atlas.

 What bandwidth-based graphs would we want Atlas to present?  I'm asking
 because I'd like to implement all bandwidth-related extensions at once.
 Note that each graph requires up to 5 KB of data per relay in bandwidth
 documents.  We should only add data for graphs that we think will be quite
 useful.  We'll also have to think about Atlas' interface, because it
 shouldn't end up displaying 6 x 6 graphs on a relay's details page.

 a) Written and read bytes (we already have those and they're actually 2 x
 5 KB per relay in size)

 b) Written and read directory request bytes.

 c) Advertised bandwidth; minimum of bandwidth rate, burst, and observed
 bandwidth as reported by the relay in its server descriptor.

 d) Consensus weight fraction as compared to all other relays in the
 network.

 e) Consensus weight fraction as compared to all other relays in the
 network having the same Exit and Guard flag as the relay in question.  If
 we provide this graph, we should use all flags that are relevant for
 clients to make path-selection decisions (are Exit and Guard the correct
 ones?).  Having graphs for single flags (e.g., comparing all relays with
 the Exit flag in a single graph) is probably too much.

 f) Consensus weight as absolute number instead of a fraction.

 There would be similar intervals for these graphs as for the current
 graphs: 3 days, 1 week, 1 month, 3 months, 1 year, 5 years.  Unless it
 doesn't make sense to include some of these intervals for some graphs, of
 course.
