Tableau dumbbell charts, also known as DNA charts, are an alternative visualization choice for illustrating the change between two data points.

I’m pleased to share the Tableau Foundation’s brand new Living Annual Report. We’ve ditched the traditional, glossy-printed annual report for a live report so anyone can get near-real-time information on what we’re doing around the globe.

Whether you’re a beginner or a Jedi, we have entire courses dedicated to helping you do more with your data. These courses have helped thousands of people to learn Tableau faster than they thought was possible.
