Data Visualization Today

I’ve always been interested in data visualization and with the amount of data being transferred with the technologies of today and the technologies available to process that data, it can really be visualized in creative and abstract fashions. Take a look at digg labs and how they visualize the data coming through their site. Certainly a big step above a Venn Diagram! At DDA I have not yet had the chance to work on a project like this but wonder how it might be applied to a medical eLearning platform in showing a users progress through the course or the results of a procedure simulation assessment.
