the pie charts in the NTA have a very retro feel, but do not provide a really good visualization of the data, you have to drill down into several pictures, but it's hard to figure out where the traffic flows are coming/going to
Here is what a sankey flow picture looks like:

what I might have on the LHS is source-port -> Source Host -> dest host -> dest port
[with the ability to add intermediate sampling routers in the middle I would get a good visualization of the physical path taken]
