In case anyone else finds this useful, I spent the time to write out some python to convert chrony's stats logs to
something that looks close enough to ntpd that ntpsec's ntpviz can graph it.
Its not perfect - "Local RMS Frequency Jitter" is just the error bound chrony reports (which seems to be something
similar, but different?) and statistics.log doesn't report an average/median RTT time, so that is filled with 0s (maybe
that would be a useful thing to provide?), but it otherwise works.
