1D visualization doesn't work?

[asinghvi17]

It looks like FerriteViz always assumes triangles are available, meaning 1D visualizations won't work. This isn't a problem for 2+ dimensional data because triangles are always available.

Is there any interest in fixing that? I just tried to visualize a system created with generate_grid(Line, (20,)) and immediately got an error:

ERROR: MethodError: no method matching ntriangles(::Line)

I think the way to go is to add a field to the plotter that can hold line information #41 (comment)

This would be of high interest, because I think there will be a lot of people that use structural elements such as trusses and beams that require 1D elements to be plotted (as well as Dennis' mentioned examples in the linked comment)

Thanks for the reference! Closing as duplicate then.
