The session aims to showcase basic functionality of two free tools: Tableau Public for tabular data visualization and Gephi for network visualization. First, the session will guide participants step-by-step through each tool based on particular data sets. Then participants will independently work on similar data sets aiming to replicate the demonstrated approaches and perfecting the visualizations. The session is suitable for participants who have not worked with the tools before. More advanced participants will benefit from feedback about their individual work. Both softwares should be pre-installed on participant's laptops. Tablet computers and netbooks are not suitable devices for the session.
