I've noticed some issues with the Y-axis units in the total page views graphs, but might be present in other graphs too. See both the attached screenshot and https://stats.wikimedia.org/v2/#/es.wikipedia.org/reading/total-pageviews
# [SOLVED BY ANOTHER TASK] The unit prefixes doesn't seem right to me. If using `m` for million, than I would expect `b` or `bn` for billions (although there is some ambiguity in the value of a billion). If instead the SI prefixes are used, I would expect `M` for mega and `G` for giga. An alternative approach could be to just use one unit per graph, write it without abbreviations at the top of the Y-axis and just use plain numbers in the labels, but might not work well if some graphs have very large range of values.
# When passing to the next scale at least one decimal is needed to provide to avoid to have two labels in the Y-axis with the same value of `1g`, at least in this case.
# [SOLVED BY ANOTHER TASK] [mostly style / usability] I'm not sure that having all the graphs starting from zero helps the readability of them. In particular when the line goes behind the legend with the date and the value of the point when mouse hovering. Not only the line is partially shadowed by the label box, but is also harder to do "mouse hover" on the points behind the label box, as the hover needs to be done outside of the box, at the same X of the point I want to hover. Is also a bit confusing, as hovering from left to right I might not notice that the hovering is "stuck" at the previous value and read the wrong value.
