A few homemade Gephi graphs:

30 Gephi examples

They illustrate the diversity of what we can do with this software and can help you conceptualize what a “network” is.

Depending on your browser, clicking on the datasets will download them. If it opens them in a webpage, “save page as” a TXT file, and then remove the .txt extension, keeping only the .csv.

Please note that these datasets are made available for demo/tutorial/training purposes. Contact me if you want to know more about them and/or use them in other contexts.

Notes
  1. 0.8.2 – Important information for users of an Apple computer running a recent version of OS X (10.7 Lion, 10.8 Mountain Lion, 10.9 Mavericks or 10.10 Yosemite) : To be able to run Gephi, you’ll have to download and install a previous version of Java (Java 6 instead of your Java 7 or 8).

    Gephi PackageDepending on your configuration, you’ll have to edit the gephi.conf file of the application. You’ll find it in the “Package Contents” of the application (right-click on Gephi in your Applications menu and click on “Show Package Contents”). Here’s the way to the gephi.conf:

    /Applications/Gephi.app/Contents/Resources/gephi/etc/gephi.conf

    At the end of this file, add this line:

    jdkhome=”/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home”

    You’ll find more ressources about this issue on Gephi forums / Gephi Facebook group / other websites. After a few attempts, do not hesitate to email me.
