plotly hover tooltips need improving

[tomjemmett]

current plotly implementation uses default tooltips, these could do with being improved

Just some screen grabs from when I was reviewing
Current UPL tooltip (needs rounding, and better label):

Current data tooltip (might need rounding for some datasets, point_type would be better as "Variation Type", and removing the snake case text would be great):

Similar points to above for the legend:

separate issue for legend in #177 🙂

#182 is an attempt to improve this, but not resolve. I've basically hacked it by string replacing on the items to remove the additional text, then used a unified x-axis hovermode to show all traces at once

We may be somewhat limited by using plotly::ggplotly, and to tackle this completely we may need to create it in {plotly} from scratch

Is there any work ongoing around improving the tooltips? I think it would be good to see the cause of the dot colour like shift above the mean for example when you hover over a dot.

I don't think anyone is working on it, so feel free to self-assign it if you'd like to...
