Back to graphs.
   Let's draw a graph! Like a map!
   Or maybe even just plot a single pixel.
   The plotting code could have a comment on it that's all "I wish I were
   a particle!"
   I've occasionally made systems that output interactive graphics since
   2013 happened.
   I made a webgl renderer that draws an interactive environment of
   spheres by calculating the ellipses that form their edges.
   I worked a little on a genetic graph display system for the center for
   disease control of my country. Very rare work, done for free and fun.
   I haven't looked at these things for some time.
   Presently I'm near a raspberry pi and an android phone. Both of these
   seem difficult and different from each other, to do pixel plotting on,
   but I could be wrong.
   Usually graphics are done with a library with many api calls, and a
   number of verbose setup and teardown routines, that interfaces with
   graphics hardware and abstracts it.
   I'd like to plot some data interactively, ideally, and I'd like to
   reuse code I write, somehow.
