A video released by Tenable Security showing a visualization of an office network is pretty wild. Using different colors and lines users can pin-point problem areas based on traffic and data being sent and received to each machine.

The system lets you call out various aspects of the network using marker shape, color, and network lines. For example, you can change symbol colors depending on vulnerabilities and even change the shape and position of mobile devices. You can see a little more of the visualization over here.
