Data Visualization

I posted an article on data visualization on the connectivism blog…and just now came across a stunning set of images that portray how data visualization is able to communicate and impact at an emotional level: An American Self-Portrait: “Each image portrays a specific quantity of something: fifteen million sheets of office paper (five minutes of paper use); 106,000 aluminum cans (thirty seconds of can consumption) and so on. My hope is that images representing these quantities might have a different effect than the raw numbers alone, such as we find daily in articles and books.”
