Why Visualize?
“You can lie and cheat with data visualiza+on.
“There is an inherent trust in the form.
“Graphs are scien+fic!”

Why Visualize?
Datavis is easy; the mechanics of it are known. Making an account is easy.
But that doesn’t tell you what happened.
Narra+ve is harder.

Why Visualize?
“The Ohh-‐Ahh Principle: Ohh! = Visual Ahh! = Learning
“Good datavis requires a balance of
Ohh! and Ahh!”
