Gephi

Gephi enables me to create beautiful, publication-ready graphical images.

I can write programs to be incorporated in Gephi.

The open-source platform provides versatility and the GUI allows easy use.

As far as my experience gephi provides good mathematical results in calculating Metrics

Its helpful as we can directly import our data which is in a .csv file

Saving the analyzed data to a .csv is a plus. Its easy to run all the metrics by single click

We can filter the columns of metrics and we can export only those we need.

Gephi has a very easy interface to use and get to the tools you need quickly. Without much training or learning, it's pretty simple to figure out.

The data import process is very easy in CSV format and the software produces a graph automatically once the correct data is loaded and mapped together (edges and nodes).

The visualization is very easy to edit, drag around, and customize. There is flexibility to change the size and color of nodes and edges to represent various characteristics of the graph.

Gephi's UI, built-in layout, and built-in clustering algorithms make it very easy to get started with (assuming you have some really data and real questions you want answered).

Gephi's force atlas layout algorithm and MCL (Louvain) clustering algorithm are both very fast, which I think is crucial for a data visualization tool, because it allows you to play with your data and do intuitive analysis.

Gephi's visualization is pretty (and intuitive), which helped me sell the clustering techniques to un-initiated and non-technical managers and executives.

Gephi has a pretty large community of support, so when I learn about other clustering algorithms/visualization techniques, it often already exists in a Gephi plug-in.

In comparison to other tools such as GraphWiz or Circos, Gephi comes with an intuitive, easy-to-use interface that makes it easy to load your data, and quickly start building all sorts of different graphs. There's absolutely no code that needs to be written for either loading or modeling. And without downloading additional plug-ins, Gephi ships with quite a few standard graph models, as well as some "fun" extras such as the Sierpinski triangle, and a variety of force atlas types.

Most of the layout types (maybe all) are highly configurable, which can make for extremely customized and unique displays of your data. Again, none of this requires the user to write any code. That said, it is possible to script custom functionality for your models, or even update the Java source code yourself, if you feel like getting technical. Gephi builds are available on GitHub, and the developers encourage people to contribute ideas, improvements, and plug-ins.

There's a plug-in for Gephi that allows for streaming data to update your model. This essentially allows you to create near realtime graphs of your data in motion. This plug-in was by far the biggest reaston we invested time in the product; to create animated data visualizations without exhaustive hours in development.
