40. Notes from discussion:
* avoid noise: colors that don’t make sense,
shapes that aren’t significant, arrows that don’t
serve a purpose. This information can be
mis-interpreted.
* if linear relationship, show it, don’t complicate
it with unnecessary info.
* is it necessary for each box to be separate?
Combine related information.
