Misc. finds while reviewing a branch

[monfera]

These are not regressions, just questions or suggestions about specific items I run into while reviewing. I may add more, in the form of comments, if I run into more.

The legend shows values of the hovered item (a relatively rare interaction and redundant in that the tooltip shows these too; sometimes the legend shows totals or other aggregations for the whole shown dataset). It seems to show the value of the last item of the series when not hovering. I wasn't sure if it's intentional

We might want to introduce default text padding for the in-bar label and the legend value too

A scrollbar appears when hovering on the last two bars

Contrast readability conflict, on dark ink the text could invert. #454

Also, the label placement can't really work with small bars stacked, maybe it'd be best to skip a label if it's outside its own ink and there's some other ink there:

Wondering about the use of the non-monotonic interpolation eg. natural, as it often overshoots the target:

The overlap of area chart with point markers may be unintentional:

@monfera can you break this issue into separate issues so we can track the work individually?

[monfera]

@nickofthyme if it's OK can we handle it as a meta-issue, or leave this task to the triager as several things might have been fixed since, otherwise it'd be just mechanical copy/paste work
