Enable curves to change into dots/circles or other shapes?

Describe the solution you'd like
Unsure whether this should be a flag or object? Unsure if data should be in main data with curves with depth or separate depth/curve object for dots?

Maybe simplify to “allow change of line width and style, with an option for no line between points”

[JustinGOSSES]

I suspect line style is independent of where actual points are (so that might not be possible as dots would not align with real values) but will look into

quick search, saving for later work:

• https://stackoverflow.com/questions/36902028/d3-lines-between-dots-not-working

plan to append circles as optional step & combined with ability to zero out the line as there is no innate d3 way to have a line appear to be circles but have the circles be positioned at the real points.

some hover tooltips work on the basis of interacting with circles over lines, so this issue relates potentially this the hover on #13 as well.
