Data Visualization Tools in Security

I have been playing with a few data visualization tools and doing some on the fly firewall log analysis. Mostly just basic plots and stuff so far.

These tools make analysis a pretty cool process. I can see where it would be useful with a very large data set.

I have been reading a new book about it, stay tuned for a review. In the meantime, there are a lot of data visualization tools out there, but I have been playing with the InspireData from Inspiration Software.  Check them out if you want to see what I am talking about.

Have you tried using visualization tools for log analysis? If so, leave me a comment about your experiences and the tools you use.
