Lunch and learns are a great way for a team to learn new things, share that knowledge with each other, and practice presentation skills. We typically do casual 30 minute sessions in a group of IT developers which range from .NET to SQL Database to Business Intelligence.
For our October, Halloween-themed presentation, I chose to give an introductory presentation on data visualization, titled “Avoiding the Horrors of Scary Visualizations: An Introduction to Data Visualization.” The presentation was targeted toward people with no background in data visualization and started with a quick history and some of the key players (Tufte and Few), bridged into some tips and best practices, and closed with a number of examples of “scary” visualization examples.
Overall, the presentation went very well and seemed to be well received. The full presentation is available here.
