In the not so distant past, data visualization was reserved for the scientific community. It helped researchers grasp the structure and relationships in large sets of data. But the explosion of complex information in most knowledge domains has changed all that.
The appreciation for visual thinking is growing and you can find many data visualizations in the popular media. Are we doing as much as we can to visualize information when we design learning experiences?
When information is visualized, it becomes tangible, which facilitates understanding. If you’re looking for new ways to visually explain complex and abstract concepts, I’ve found that it helps to play around with data visualizations. Here are four compelling examples where you might find inspiration. The last three are highly interactive.

That alone is a powerful design lesson for all of us. See How Different Groups Spend Their Day.
This visualization describes a disease network and the correlation between conditions. The health conditions can be viewed by gender and in two different layouts.
