Comment (by karsten):

 I gave this a try this morning:

 [[Image(dirbytes-2020-03-04.png, 700px)]]

 I'm not convinced yet that this visualization is better. I think the
 January 2020 situation is a typical example for stacked area graphs not
 working so well: it's very hard to say whether the "Directory mirrors"
 area changes during that time. I know that we're using stacked area plots
 in other cases, but in those cases the relative fractions remain roughly
 the same.

 Another issue is that, while read/write scales are more appropriately
 sized for their actual values now, it's now more difficult to compare
 their absolute scales.

 I'll leave this here for further discussion and continue deployment of the
 updated database in the background. Changing the graph is easy, even in
 one or two weeks from now.

 Thanks for the fast review!
