Thank you, John. Yes. And learning to communicate in pictures also lets students compare the relative effectiveness of pictures with words vs words alone. Language alone isn't enough anymore, nor are numbers. A wonderful blog for thinking about how to guide a reader's eye in an honest way is Cole Nussbaumer's Storytelling with Data <http://www.storytellingwithdata.com>. She's clearly channeling Edward Tufte, but she understands the speed at which most of us work and helps any ethical data presenter do the right thing for the reader or viewer.
