Data Visualization Review: Gephi, Free Graph Exploration Software

Data Visualization Review: Gephi, Free Graph Exploration Software
I do not often get to play with networks, yet I find them fascinating and full of knowledge gathering potential. The data visualization works of Moritz Stefaner, Jer Thorp, and Mark Lombardi captivate me. I am intrigued by relationships, how we perceive them, and how we can understand them. Gephi, the "Open Graph Viz Platform", is not just for the hobbiest node nerd. It is a hardcore, professional tool for network researchers and other smarty pants. If you know the difference between Yifan Hu and Fruchterman Reingold, then you can use this tool effectively. So what is Gephi capable off? Gephi interface displaying airline traffic data. Pros — Options! Cons — Interface is a bit cluttered. Main interface displaying the Diseasome data. Review Overall, Gephi is a useful and interesting tool. There are some plugins available for Gephi that extend the functionality. The only thing keeping Gephi from being a professional grade tool is its bugginess and lack of documentation.

Freddy: Yes, I am Dr. Frederick Fronkonsteen, newly arrived from America. Introduction to behavioral economics Just days ago, President Obama issued this executive order: A growing body of evidence demonstrates that behavioral science insights -- research findings from fields such as behavioral economics and psychology about how people make decisions and act on them -- can be used to design government policies to better serve the American people. So just what is behavioral economics?

20+ Tools to Create Your Own Infographics A picture is worth a thousand words – based on this, infographics would carry hundreds of thousands of words, yet if you let a reader choose between a full-length 1000-word article and an infographic that needs a few scroll-downs, they’d probably prefer absorbing information straight from the infographic. What’s not to like? Colored charts and illustrations deliver connections better than tables and figures and as users spend time looking back and forth the full infographic, they stay on the site longer. Plus, readers who like what they see are more likely to share visual guides more than articles. While not everyone can make infographics from scratch, there are tools available on the Web that will help you create your very own infographics.

XML provides flexible data generation, and Flash provides the best graphic quality. Fruchterman Reingold · gephi/gephi Wiki The Fruchterman-Reingold Algorithm is a force-directed layout algorithm. The idea of a force directed layout algorithm is to consider a force between any two nodes. In this algorithm, the nodes are represented by steel rings and the edges are springs between them. The attractive force is analogous to the spring force and the repulsive force is analogous to the electrical force. The basic idea is to minimize the energy of the system by moving the nodes and changing the forces between them. For more details refer to the Force Directed algorithm.
