Gephi, an open source graph visualization and manipulation software. The Gephi Consortium. RDF Graph visualization tools « Time rolls on. Large-scale RDF Graph Visualization Tools. AI3 Assembles 26 Candidate Tools The pending UMBEL subject concept “backbone” ontology will involve literally thousands of concepts.
In order to manage and view such a large structure, a concerted effort to find suitable graph visualization software was mounted. This post presents the candidate listing, as well as some useful starting resources and background information. A subsequent post will present the surprise winner of our evaluation. Starting Resources See Various Example Visualizations For grins, you may also like to see various example visualizations, most with a large-graph bent: Software Options Here is the listing of 26 candidate graph visualization programs assembled to date: Cytoscape – this tool, based on GINY and Piccolo (see below), is under active use by the bioinformatics community and highly recommended by Bio2RDF.org GINY implements a very innovative system for sub-graphing and allows for stunning visuals.

Think about your friends from high school, college, work, the city you used to live in, the ones that liked you ex- better, etc. When exploring a social network it is important that we understand not only the strength of the relationship now, but over time. We can use communication between people as a measure. I ran into a visualization that explored how multiple parties where connected by communications in multiple projects. We’re going to reuse it to explore how multiple people interact with each other. So let’s make a network of 50 friends and connect them to each other multiple times. Think of it as people writing on your facebook wall. Let’s give our network a little something special.
The code to create a relationship is pretty simple, we’ll use the Batch commands again and reference the nodes we create. Let’s put it together to create our graph. We spent some time getting our data into our graph, now let’s get it all back out. Like this: Graph database. Database that uses mathematical graphs to store and search data Graph databases differ from graph compute engines. Graph databases are technologies that are translations of the relational online transaction processing (OLTP) databases. On the other hand, graph compute engines are used in online analytical processing (OLAP) for bulk analysis.[5] Graph databases attracted considerable attention in the 2000s, due to the successes of major technology corporations in using proprietary graph databases,[6] along with the introduction of open-source graph databases.
One study concluded that an RDBMS was "comparable" in performance to existing graph analysis engines at executing graph queries.[7] History[edit] Graph structures could be represented in network model databases from the late 1960s. Labeled graphs could be represented in graph databases from the mid-1980s, such as the Logical Data Model.[10][11] Commercial object databases (ODBMSs) emerged in the early 1990s. Background[edit] Graph-database.org. Marko A. Rodriguez. HyperGraphDB - A Graph Database. HyperGraphDB is a general purpose, extensible, portable, distributed, embeddable, open-source data storage mechanism. It is a graph database designed specifically for artificial intelligence and semantic web projects, it can also be used as an embedded object-oriented database for projects of all sizes. The system is reliable and in production use is several projects, including a search engine and our own Seco scripting IDE where most of the runtime environment is automatically saved as a hypergraph.
HyperGraphDB is primarily what its carefully chosen name implies: a database for storing hypergraphs. While it falls into the general family of graph databases, it is hard to categorize HyperGraphDB as yet another database because much of its design evolves around providing the means to manage structure-rich information with arbitrary layers of complexity. For instance, a relational as well as an object-oriented style of data management can be emulated.
