AfterGlow 1.x is a collection of scripts which facilitate the process of generating link graphs. AfterGlow 1.x is written in Perl and is meant to be used on the command line. There is no graphical user interface available. AfterGlow expects a CSV file as input and generates either an attributed graph langugage file that can be processed by the graphiviz libraries, or it can generate output for consumption by the large graph library (LGL).

AfterGlow 2.0 is written in Java and generates treemaps. It takes the same kind of input as AfterGlow 1.x.

The two main datasets that I had to visualize lately were network packet captures (pcap files) and email logs (sendmail). I spent some time generating parsers for tcpdump (pcap) output and sendmail log files to convert them into csv output.
