Being able to effectively communicate your data to an audience is a necessary part of any project. How to harness visualization tools to tell a story will be presented in this short workshop. We will discuss how different types of graphs and charts are perceived and how they can be used to answer different questions. Tableau Public is a free data visualization tool. You can create interactive graphs, dashboards, maps and tables from virtually any data. You need to create an account (free) in order to be able to download Tableau and save your work. Laptops are required.
