I found this interesting blog post that brought the following to my attention. Yahoo! Mail data is now readily available for people to see through their visualization site
here. It's cool but I have a hard time understanding how to read the data.
For example, it's not clear what the size of the bubbles means. I'm guessing it represents the number of emails being sent. When I click on the bubble, I actually have no idea what the animation represents. When I click on one of the email images, it gets even more confusing. Play around with it and you'll know what I mean.
More importantly, what is an average user suppose to do with this data? It doesn't tell anything that I could use to better use Yahoo! Mail.
This visual analysis tool gets a 10 on the cool factor but gets a 1 for relevancy.
