Abstract:
Visone (ital. mink) is a free software tool that combines comprehensive means for analysis with unique visualization capabilities. It can also be used as a graphical frontend to R, RSiena, and KNIME.

This is a hands-on introduction to visone. After a brief overview of its design and features, we will explore some of its core functionality. Using exemplary network analyses, we will produce presentations of findings step-by-step, starting from data input to arrive at publication quality information visualizations, including time-coherent animations of longitudinal networks.

It is advisable to bring a laptop running Windows, MacOS, or Linux. The software is written in Java and can be installed from www.visone.info. It features many standard and non-standard methods for analysis and visualization of networks, and a powerful graphical user interface. It's native file format is GraphML, allowing for arbitrarily many attributes of nodes, links, and networks, but other formats such as CSV tables, UCINet DL, Pajek .net, etc., can be imported. Visualizations can be exported as pdf, png, tiff, animated svg, or Windows metafiles.
