Explore summary plots/graphics to provide better big picture #52
Description
Back-burner issue once we've taken care of the main stuff.
HTAN has some summary graphics like below. We should think about what could be put into a nice summary graphics page. (Not tumor sites, though, because we're not going to have a large diverse set of tumor sites, but things like assays could still apply.)
@cconrad8 and @inodb for any ideas
