I wrote a small blog post about AfterGlow and how to visualize packet captures. It gives a few examples on how packet captures can be visualized as link graphs.
I then followed up with a post on Advanced Network Graph Visualization with AfterGlow. In this post I show how you can use some extended capabilities of AfterGlow to read configuration parameters from variables and files in order to influence your network graph's colors, clustering, etc.
Curious to hear your feedback!
