Learn how to use Gephi
Welcome to Gephi! Gephi is an open-source software for visualizing and analysing large networks graphs. Gephi uses a 3D render engine to display graphs in real-time and speed up the exploration. You can use it to explore, analyse, spatialise, filter, cluterize, manipulate and export all types of graphs. Getting Started New to Gephi?

10 Awesome Free Tools To Make Infographics Advertisement Who can resist a colourful, thoughtful venn diagram anyway? In terms of blogging success, infographics are far more likely to be shared than your average blog post. This means more eyeballs on your important information, more people rallying for your cause, more backlinks and more visits to your blog. In short, a quality infographic done well could be what your blog needs right now. Designing An Infographic

Text Network Analysis Text network analysis allows one to quickly visualize the meanings and agendas present within a text, live conversation, broadcast, or interview. Our method is different to semantic network analysis. Instead, we focus predominantly on the relationships and clusters of meaning present within the text, uncovering what we call the pathways for meaning circulation Our interest lies in researching the topology of the resulting network, allowing us to focus on a text as a whole rather than its specific semantic parts. These topologies can then be compared with our extensive database in order to sort texts according to their structure rather than arbitrary categories they belong to.

I had a look at the reusable method and I think that the function saveAsGEXF could be improved as saveAsGEXF = function(g, filepath="converted_graph.gexf") require(igraph) require(rgexf) 22 free tools for data visualization and analysis You may not think you've got much in common with an investigative journalist or an academic medical researcher. But if you're trying to extract useful information from an ever-increasing inflow of data, you'll likely find visualization useful -- whether it's to show patterns or trends with graphics instead of mountains of text, or to try to explain complex issues to a nontechnical audience. There are many tools around to help turn data into graphics, but they can carry hefty price tags.

GraphChi Disk-based large-scale graph computation Introduction GraphChi(huahua) is a spin-off of the GraphLab(rador) project. GraphChi can run very large graph computations on just a single machine, by using a novel algorithm for processing the graph from disk (SSD or hard drive). Programs for GraphChi are written in similar vertex-centric model as GraphLab. GraphChi runs vertex-centric programs asynchronously (i.e changes written to edges are immediately visible to subsequent computation), and in parallel.

Social Network Analysis using R and Gephis After learning the basics of R, I decided to learn something harder last week. 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. Social Network Analysis About the Course Everything is connected: people, information, events and places, all the more so with the advent of online social media. A practical way of making sense of the tangle of connections is to analyze them as networks. In this course you will learn about the structure and evolution of networks, drawing on knowledge from disciplines as diverse as sociology, mathematics, computer science, economics, and physics. Online interactive demonstrations and hands-on analysis of real-world data sets will focus on a range of tasks: from identifying important nodes in the network, to detecting communities, to tracing information diffusion and opinion formation.

Cytoscape: Hands-down Winner for Large-scale Graph Visualization I still never cease to be amazed at how wonderful and powerful tools are so often and easily overlooked. The most recent example is Cytoscape, a winner in our recent review of more than 25 tools for large-scale RDF graph visualization. We began this review because the UMBEL subject concept “backbone” ontology will involve literally thousands of concepts. Graph visualization software suitable to very large graphs would aid UMBEL’s construction and refinement. Cytoscape describes itself as a bioinformatics software platform for visualizing molecular interaction networks and integrating these interactions with gene expression profiles and other state data. Cytoscape is partially based on GINY and Piccolo, among other open-source toolkits.

Tutorial Visualization This is an introduction tutorial about visualization in Gephi. It will guide you to the basic and advanced visualization settings in Gephi. The selection and interaction with tools will also be introduced. Available in other languages: Japanese UCINET Software UCINET 6 for Windows is a software package for the analysis of social network data. It was developed by Lin Freeman, Martin Everett and Steve Borgatti. It comes with the NetDraw network visualization tool. If you use the software, please cite it.
