A little over a year ago, I submitted to Nathan few graphs I made out of some SSH/FTP usage stats I had extracted with few lines of a prototype code. Now I finally had the time to make a full-fledged datavis application with textual and graphical means to convey some info about your login activities (local machine or remote server).
You can submit your data and have it visualized.
Here's the url:
