Making Data Easy To Understand
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.
Although it might be difficult to understand 1 trillion dollars, the BBC found a simple way to explain this numeric concept. It starts with a door mat as one unit and expands from there.

It takes a minute for the whole thing to load. See 1 Trillion Explained.
The New York Times excels in interactive data visualizations. They have the staff and the vision to create interactive graphics that help you see information in new ways and to draw your own conclusions. This particular example may reveal much about the culture and society of the US. In terms of online learning, you get a lot here just by playing around. 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. You can select diseases and condition from a list of categories and then roll-over each circle for the specifics. Notice how changing the layout changes how you perceive the relationship of the information. See Health Infoscape.
