Beware Analysis That Lacks a Graph

If you're digging-into, or generating, numbers (spreadsheet), you probably need a visual "interface" to them. Make a graph!

I've seen so many analyses go off the rails because people don't realize how ridiculous their projections are, or that an analysis is inaccurate because of a tiny number of edge cases, etc.

Every calculation is a model. A visual output helps you catch dubious assumptions in your model.
