When creating a graph to explain something to someone else, I recommend that you declutter and focus attention. These concepts are not new. We have taught and written about them—directly and indirectly—many times before. I wrote about them again when drafting my new book, but then decided to take a different approach. Rather than relinquish my original words to a dismal fate in my computer’s trash bin, I thought perhaps they might still be of use here. After all, even if we’ve shared good advice before, sometimes it bears repeating.
Those are great general principles and Cole has specific examples of the principles in action.
