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.

Oldcastle wasn’t consuming its data in the most efficient way. And as North America’s leading manufacturer of building products and materials (“masonry and hardscapes, otherwise known as sexy concrete,” says Ian), the company had a lot of data.
