What does this graph show? Can you describe it in a single sentence? Franconeri explains that many people, even highly educated college stu - dents, say that it clearly depicts a person walking up and down a hill, or escalators in a mall, or perhaps an airplane taking off and landing. “That’s treating the graph like a picture from a camera. It’s using the part of your brain that is practiced in seeing and understanding the world outside,” he says. What this graph is actually depicting is an object that starts off moving (in any direction), then stops moving (because time continues changing, but the position is not changing), then moves again. “A visualization is not a 50-millisecond view, where you look at it and you understand what’s happening. It’s a minute-long process,” says Franconeri. 5. The way that you organize the data controls the pattern that the eye will see. If visualizations need to be read, what controls how you will order each of the “sentences”?
