Two-by-two matrix, useful in lots of SenseMaking

hmm is any 2-axis graph/diagram equivalent to a 2x2?

Venkatesh Rao loves to make them.

hmmm, 3D → 2x2x2?

  • Venkatesh Rao on how to draw them in 2D: inscribe a circle to add an in/out third dimension. Don’t use a diamond. X’s are totally out. Isometric cubes will get you executed on the spot.

Does a Pros and Cons table count (if you're only comparing 2 ideas)?
