Data visualization gives us a better understanding of our data and helps us communicate that to others. It has the potential to generate insights, communicate findings, and illustrate evidence. Conversely, a poor visualization can undermine an argument or even mislead the reader. Through a combination of lecture and demonstrations, this 1.5-hour online workshop will provide a brief introduction to data visualization theory and practice, mainly focusing on using a common data visualization tool, Tableau Desktop. Participants will create visualizations such as a bar graphs, line graphs, scatter plots, and dashboards. The workshop is free and open to all. It will be held on zoom. Pre-registration is required.
