visualization

“A picture is worth a thousand words” goes the old saying.

If that’s the case, then an infographic like this one is far more valuable. (click to see it full size in a new window)

This is from the National Geographic Blog and clearly illustrates several factors in the debate over national health care in ways that pages of text never can.

Do we teach our students to interpret information in this form? More importantly, do we teach them how create a visualization of data similar to this one?

Or do we just teach them to read?

On the mathematical side of things, one thing the chart shows most effectively is that there is no direct correlation between amount of money spent per person for health care and at least one desirable effect: life span.

What else might students (and others) read in this picture?

A Snapshot of Your Online Identity… Maybe

I’m not sure what to think of this.

The graphic (click to see a full size version) was created by Personas, a project of the Sociable Media Group at the MIT Media lab and which according to their web site, creates a “data portrait of one’s aggregated online identity. In short Personas shows you how the Internet sees you”.

Interesting, since in almost seven years of ranting in this space, I don’t remember writing much if anything about sports, fashion, or religion. (Of course, there’s always the possibility that my name isn’t as unique as I’m assuming it is. :-)

Another factor that gives me doubts about the accuracy of this particular portrait is that in repeating the process, the sports stayed but the fashion and religion vanished, even though it seemed to be analyzing the same sources each time.

Anyway, it’s still fascinating to watch the visualization being built and, as the developers refine the underlying algorithm, this could be a wonderful tool to use with students (or adults) to get a snapshot of themselves online.

And as a starting point for a discussion of how it got there.
