We briefly talked about this on IRC.  There are already quite similar
graphs that you want in b):

https://metrics.torproject.org/advbwdist-perc.html

https://metrics.torproject.org/advbwdist-relay.html

The graph you describe in a) is more difficult.  I haven't made up my
mind entirely here, but I think this graph doesn't fit on Metrics, but
rather a site or service dedicated to monitoring the network for
attacks or bugs.  Philipp's Sybil attack detector comes to mind.

But more generally, when we think about adding graphs to Metrics and
automating them, we should start with manually-created graphs first.
If we like them enough that we want to automate them, putting them on
Metrics is an option.

All the best,
Karsten
