skitter viz using hypviewer
skitter and hypviewerRecently I spent a couple of days porting the hypviewer library to Solaris 2.7 and FreeBSD 3.1. Hypviewer is a library for viewing large graphs. It uses a layout in hyperbolic space and projects the space into a unit sphere. Hypviewer was developed by Tamara Munzer at Stanford University.
I've written a quick program to convert skitter data (in ARTS format) to the format used by the hypviewer file reader. Here are some initial results viewing a large skitter dataset for source riesling.caida.org, with roughly 29,000 destinations. This dataset is from February 18th, 1999.
Note that links are reddish in color on their way out of a node and blue on their way in to a node.
It should be noted that all of the screenshots above were taken from a single run on a single dataset. It's difficult to appreciate this software until you play with it and start realizing its potential. Not so much as a visualization system in and of itself, but as a powerful navigation system for network measrement data. There are interfaces for node and link selection, node searching and animated navigation, grouping, etc. which could prove useful when tied to a user interface for large skitter datasets.
