Open Source Data Visualization Software

Visit our new site: http://socnetv.org Social Network Visualizer (SocNetV) is a social network analysis and visualization application. You can draw a social network (graph/digraph) or load an existing one (GraphML, UCINET, Pajek, etc), compute cohesion, centrality, community and structural equivalence metrics and apply various layout algorithms based on actor centrality or prestige scores (i.e. Eigenvector, Betweenness) or on dynamic models (i.e. Kamada-Kawai spring-embedder)

Egonet is a program for the collection and analysis of egocentric network data. It helps you create the questionnaire, collect data, and provide general global network measures and data matrixes that can be used for further analysis by other software. Source code is hosted at http://github.com/egonet/egonet.

JUNG provides a common and extendible language for the modeling, analysis, and visualization of data that can be represented as a graph or network. New version now available on GitHub: https://github.com/jrtom/jung/releases/tag/jung-2.1

On The Mark is a video and image scoring system that allows one to mark any number of events and durations through a simple, easy-to-use graphical interface.

Diagram (JGraph) driven simulator. Bondgraphs > nonlinear differantial system > plot: implemented for economics and ecology. Network analysis: emergy propagation implemented. Would also fit for electronics, mechanics, cost, GWP, footprint analysis.

@rbre uses X3D to let people create, visualize, browse and share genealogical data, by using 2D individual icons assembled in 3D family trees. @rbre will include P2P functions for sharing.

Atavi is an interactive genealogical data visualization tool. It uses XSLT to transform XML data into SVG (Scable Vector Graphics) images. Deploy it as a Java servlet and explore visualizations from a browser that supports SVG. GEDCOM import is planned.

The Crosswise project is a web-based community event calendar that adds modular data analysis and visualization, and communication methods, to provide community organizations with a powerful event planning, collaboration and analysis tool.

Controversial ideas of Williamson, Margulis & others suggest speciation by hybridizing might be more common than originally thought. Taking this concept to the nth degree & assuming that indeed, speciation mostly occurs by hybridizing events, not the accumulation of mutations or genetic drift, here is a catalogueoflife2gedcom converter. It allows the tree of life to be displayed as a human genealogy tree with hybridizing events depicted as "marriages." The idea then is that mutation accrual & genetic drift are the determining factors for "species maturation," not speciation itself. Unfortunately the Catalogue of Life Project, catalogueoflife.org, changed its database format more recently, so this converter only works on older versions of the data. In the last working version of the database, making the assumption that each taxonomic name, no matter what level, refers to an original real species & starting them all as female, over 2 million "species/persons" were generated.

Graphl is a generic graph visualization and manipulation tool written in Java. Graphl reads and writes RDF files, visualizes them in a flexible and customizeable way and allows users to edit them intuitively. Please see project homepage for more info...

A rich client to analyse data from a liquid-feedback (http://liquidfeedback.org/) instance, for now it's a 3d graph explorer to inspect the delegations. It's an application based on the eclipse platform (indigo). To be precise its a directed weighted multi graph browser in 3d.
