On this site we collect links, code and ideas about how we can visualise and navigate graphs.
In mathematics and computer science, Graph Theory is the study of graphs, which are mathematical structures used to model pairwise relations between objects.
A "graph" in this context is made up of vertices or nodes and lines called edges that connect them. A graph may be undirected, meaning that there is no distinction between the two vertices associated with each edge, or its edges may be directed from one vertex to another

Graph drawing is an area of mathematics and computer science combining methods from geometric graph theory and information visualization to derive two-dimensional depictions of graphs arising from applications such as social network analysis, cartography, linguistics, and bioinformatics - wikipedia
Here we look at how to work with maps in wiki. In particular we want to look out how we can use wiki to create and document walks, oral histories, and map festivals.
He we list a few pages and sites about graph and network visualisation as it relates to FedWiki.
Here we look at tools for data visualisation for Platform Earth and wiki.
There are some great docs - js.cytoscape.org
Graphviz (short for Graph Visualization Software) is a package of open-source tools initiated by AT&T Labs Research for drawing graphs specified in DOT language scripts. It also provides libraries for software applications to use the tools. Graphviz is free software licensed under the Eclipse Public License - wikipedia
Neo4j is an open-source graph database implemented in Java and accessible from software written in other languages using the Cypher query language through a transactional HTTP endpoint -
Tulip is an information visualization framework dedicated to the analysis and visualization of relational data. Tulip aims to provide the developer with a complete library, supporting the design of interactive information visualization applications for relational data that can be tailored to the problems he or she is addressing - wikipedia
Vega is a visualization grammar, a declarative format for creating, saving and sharing interactive visualization designs.
I'd like to view a graphviz file in wiki. I can process it on the server but it seems difficult to get any rich format to display on the screen. Of course I want links so this makes image formats a non-starter.
Gephi is an open-source network analysis and visualization software package written in Java on the NetBeans platform - wikipedia
Simulation is the imitation of the operation of a real-world process or system over time. The act of simulating something first requires that a model be developed; this model represents the key characteristics, behaviors and functions of the selected physical or abstract system or process. The model represents the system itself, whereas the simulation represents the operation of the system over time - wikipedia
It has not really been possible until very recently to represent large interactive graphs visually, and especially not on the web.
Here we look at how we might visualise the Federation, and explore using Cytoscape to achieve a scaleable ability to visualise the network of links and in particular Network of Forks relevant to a particular writing context.
