I have mixed feelings about this article. On the one hand, after looking at an image of the mangled presentation, I can certainly agree that the message could have been a lot clearer. But I'm not sure storytelling is what we need here. Yes, true, a press conference is a presentation, and presentations are linear narratives. But the visual aids need not be linear (and after presenting today I'm feeling that I should be adding an 'explorable' resource to each presentation I make. I agree with this, though: "Good visualization is key to making sense of data. By understanding the grammar of graphics (26 page PDF) we can learn how to encode data visually to make it both aesthetic and meaningful."
