::fibreculture:: Gephi .. Exploratory Data Analysis

[stephen at melbpc.org.au]

Powerful science .. your own Hubble telescope, for patterns in any data.


Gephi. Runs on Windows, Linux and Mac OSX, Gephi is open-source and free.

Like Photoshop, but for data, the user interacts with the representation, 
manipulates the structures, shapes and colors to reveal hidden properties 

The goal is to help data analysis, to make hypothesis, intuitively 
discover patterns, isolate structure singularities or faults during data 
sourcing. 

It is a complementary tool to traditional statistics, as visual thinking 
with interactive interfaces is now recognized to facilitate reasoning. 

This is a software for Exploratory Data Analysis ...

"EDA development: Tukey held that too much emphasis in statistics was 
placed on statistical hypothesis testing (confirmatory data analysis); 
more emphasis needed to be placed on using data to suggest hypotheses to 
test."

Gephi: An Open Source Software for Exploring and Manipulating Networks

 by Mathieu Bastian, Sebastien Heymann, Mathieu Jacomy

Abstract: Gephi is an open source software for graph and network 
analysis. It uses a 3D render engine to display large networks in real-
time and to speed up the exploration. We present several key features of 
Gephi in the context of interactive exploration and interpretation of 
networks. Gephi provides easy and broad access to network data and allows 
for spatializing, filtering, navigating, manipulating and clustering. 
Finally, by presenting dynamic features of Gephi, we highlight key 
aspects of dynamic network visualization."
