Gephi is an amazing visualization tool. It is user friendly and the GUI is very self explanatory . It is the best tool for network analysis. It allows us to easily apply various filters on the network graph to make the graph more readable. We can calculate many statistical parameters such average degree, clustering coefficient, network diameter, modularity etc. We can then change the size and color of nodes according to the parameters for analyzing the network. It also allows us to save all graphs.

Through this tool you can analyze quantitative and qualitative data. Personally I have been able to do text analysis and at the same time data of variables of level reason like velicidad of automobiles. The best thing about this software is to be able to apply filters, statistical models, analysis schemes and still opt for very interactive and pleasing visuals.

I am competent in using R to do social network analysis, and even then I prefer to use Gephi to visualize large networks. Gephi also provides some important measure results such as closeness, betweenness and eigenvector centralities, and one does not have to know programming in order to get these results, which makes the program very convenient to use. With add-ons, it is also possible to create dynamic networks publishable on the web.
