GUESS - The Graph Exploration System

Open Source Graph Visualization Tool

GUESS is an exploratory data analysis and visualization tool for graphs and networks. The system contains a domain-specific embedded language called Gython (an extension of Python, or more specifically Jython) which supports the operators and syntactic sugar necessary for working on graph structures in an intuitive manner. An interactive interpreter binds the text that you type in the interpreter to the objects being visualized for more useful integration. GUESS also offers a visualization front end that supports the export of static images and dynamic movies.

Walrus - Graph visualization software

Open Source Graph visualization Tools

Walrus is a tool for interactively visualizing large directed graphs in three-dimensional space. It is technically possible to display graphs containing a million nodes or more, but visual clutter, occlusion, and other factors can diminish the effectiveness of Walrus as the number of nodes, or the degree of their connectivity, increases. Thus, in practice, Walrus is best suited to visualizing moderately sized graphs that are nearly trees. A graph with a few hundred thousand nodes and only a slightly greater number of links is likely to be comfortable to work with.

LibLime Koha

LibLime Koha is the most advanced open-source Integrated Library System in use today by hundreds of libraries worldwide. LibLime Koha is web based, so there is no software to install on desktop computers, and LibLime hosting services means that no servers are required in the libraries. LibLime's IT experts manage all upgrades, backups and general system maintenance, and the Library's local IT staff can focus on the Library's many other projects.

Evergreen - ILS

Open source Integrated Library System

An open source ILS (integrated library system) used by over 1000 libraries around the world. The software, also called Evergreen, is used by libraries to provide their public catalog interface as well as to manage back-of-house operations such as circulation (checkouts and checkins), acquisition of library materials, and (particularly in the case of Evergreen) sharing resources among groups of libraries.
