Education Visualization

I'm not sure if this exactly counts as a straight-up information visualization such as those we usually talk about during class, but I found it to be a very interesting visualization nonetheless. It's a fairly simple concept: the student-teacher ratio in k-12 schools across the country, but I found the way they presented it to be very clever. They presented it in such a way that all the elements matter, from the color of the book, to the size of the locker, to it's arrangement and everything. That's how I feel most visualizations should be, making everything matter - but making it so that even at one glance, the reader gets an immediate sense of what you're trying to say, and it stands out enough so that it sticks with them for a long while.
