Yesterday I had the honor to speak at the Show me the Data 2012, a conference in Amsterdam that also featured talks by Alberto Cairo and Jan Willem Tulp. In my presentation I explained how in my opinion data visualization can benefit form research in multimedia learning. At the end, I called for more experiments with visualizations that combined interactivity with verbal narration. So, to put my money where my mouth is, I edited my talk a bit and created this interactive audio slideshow.
The video mentioned in the second last slide is The Value of Data Visualization.
