Could this be a self.assertIs?

I was looking at this on Wikipedia (https://en.wikipedia.org/wiki/French_invasion_of_Russia#/media/File:Minard.png), and it looks like the temperature may be in degrees Reaumur.

I got a bit bored on a long weekend.
This PR adds a general segment plot, which is a collection of (disconnected) line segments specified by start and end points. Segments can be mapped by width and color as well as position.
Also added a plot which draws text at specified x and y locations, similar to the 1d text plot that already exists.
