This post lays out some of the importance of interactivity for network diagrams and we think is well worth a read (or at least a skim!)

; however, if you wish to skip to the demos, these are linked at the end of the post. Visualizing network data is a prime example of a research activity where both desktop tools and online libraries exist, but are not well connected with one another. Desktop software like NodeXL and Gephi provide the ability to collect and visualize network data (users on Twitter, videos on YouTube, etc.). These applications, however, provide limited facilities for hosting, sharing, and optimizing visualizations for the web. Visualising Advocacy. Facebook-class social network analysis with R and Hadoop. Social network analysis often amounts to calculating the statistics on a graph like this: the number of edges (friends) connected to a particular node (person), and the distribution of the number of edges connected to nodes across the entire graph.

Facebook-class social network analysis with R and Hadoop

When the graph consists of up to 10 billion elements (nodes and edges), such computations can be done on a single server with dedicated graph software like Neo4j. But bigger networks — like Facebook's social network, which is a graph with more than 60 billion elements — require a distributed solution. Marko A. Rodriguez, a graph consultant with Aurelius, shows in a blog post how to use R and Hadoop (integrated with Revolution Analytics' RHadoop packages) to analyze Facebook-scale social networks. He first simulates a social network (shown at the top of this post) using R's igraph package, and then distributed the network in the Hadoop cluster with to.dfs function (from the rhdfs package).

Enterprise Software Doesn't Have to Suck: Social Network Analysis using R and Gephis

I picked Social Network Analysis (SNA) to learn the concepts of SNA and R. My primary interest in SNA is visual exploration of networks, so I needed to find a tool first. Overview — NetworkX 1.6 documentation. SocialAction. SocialAction is a social network analysis tool that integrates visualization and statistics to improve the analytical process.


A journal article about SocialAction was recently published in IEEE Computer Graphics and Applications. See the full details in the papers below. SocialAction won a VAST Mini-Challenge award for uncovering hidden structure in social networks over time. There are also two recent conference publications about SocialAction!

By using business data, we can learn about the links between our customers and just as importantly, which customers have a strong social influence. We can use this insight to create a competitive advantage. Social Network Analysis for telecoms & gaming. Reduce Churn & Improve Marketing Front. DyNet Software. The purpose of the DyNet project is to develop the equivalent of a flight simulator for reasoning about dynamic networked organizations.

DyNet Software

Through a unique blending of computer science, social networks and organization theory we are creating a new class of tools for managing organizational dynamics. The core tool is DyNet - a reasoning support tool for reasoning under varying levels of uncertainty about dynamic networked and cellular organizations, their vulnerabilities, and their ability to reconstitute themselves.

Using DyNet the analyst would be able to see how the networked organization was likely to evolve if left alone, how its performance could be affected by various information warfare and isolation strategies, and how robust those strategies were in the face of varying levels of information assurance.
