Add feature for selecting which series are visible in the plot
It'd be nice to be able to filter out certain series to have less noise in the plot.

Potential UX:
* Similar series are grouped under one toggle (e.g. legend)
* User can click the toggle to hide/show the series belonging to that group
* Naming of these groups?
